Plastic bag uses plastic as original materials, be used to product the packing bag of all kinds of products, widely used in daily life and industrial production. Food plastic bags are often used in people's life, but also must be careful when you use them, some plastic bags are toxic, cannot be used directly to the food. So, how to identify health and safety plastic bags? There is the several ways to follow:

1. Observing with eyes. Non-toxic plastic bags usually is white, transparent or slightly transparent, with uniform texture; Toxic plastic bags are usually colorful or is white, but the transparency is poor, epinephelos, surface of plastic not tensile uniform, with small particles. 

2. Listening with ears. Use hand shaking strenuous, plastic bags show clear sound that is non-toxic plastic bags; And sound small, stuffy is poisonous plastic bags. 

3. Touch by hand. With the hand touching surface of plastic packaging bags, very smooth that is non-toxic; Sticky, acerbity, waxy feeling is toxic. 

4. Use nose to smell. Non-toxic plastic bags are tasteless; Have stimulating smell or abnormal smell that is toxic. 

5. Submerged test method. Put plastic bags into the water, press it to the bottom, just a moment, the surfaced one is non-toxic plastic packaging bags, sink into the bottom is toxic plastic bags.
    
The 21st century is the century of environmental protection, construct circular economy society, sustainable development has become a global focus and urgent task, in order to adapt to the demands of a new age, plastic packaging materials in addition to the requirements to meet the market of packaging quality and quantity increasing requirements, its starting point of development must be the technology development to save resources, easy to recycle after used, or easy to be environment given or degradation. Anti static plastic bags is composed of inside and outside layer transparent anti-static materials, in the middle is translucent conductive metal layer, thus has good anti-static, electrostatic shielding, moisture-proof performance. The development of plastic anti-static bags has experienced four distinct phases: the original bags, big bags, small bags, now entering a new stage of environmental protection (green) packaging. New material, new craft, new technology, new products of plastic packing constantly emerge, and developing to the direction of high performance, multi-function, active adoption of new materials, new technology, broadening the application field and plastic packaging and environmental protection compatible development.

There are many kinds of packaging, food bags, pet food bags, flower bags, medicine packaging bags, and electronic packaging bags. Most suppliers love wholesale packaging bags. With the increased importance placed on self-service marketing, the role of packaging is becoming quite significant. In actual operation of food green packaging design, designers will generally take into account whether packaging materials will cause some of the environmental and human health hazards, but little attention they will pay to potential environmental and human health hazards from ink in the process of packaging printing. Thus, food packaging paper tableware wholesale manufacturers will also not concern about those hazards. food packaging bags can be used in food after printing. Designers often use brilliant colors to catch the eye of and recognition consumers and to achieve their promotional function. In the color design of food packaging, designers unscrupulously use colors.

Currently paper tableware wholesale printing mainly uses solvent-based inks, which contain some heavy metals, residual solvents, volatile organic compounds that may cause pollution to food through chemical migration. Inks contain hazardous solvents such as benzene, toluene, and xylene. If benzene exceeds standards, it will give rise to blood system diseases and cancer. In addition, heavy metals such as mercury, lead, arsenic and other content inks in inks also do great harm to the human body. Unqualified food packaging will have a negative impact on human health when being used, especially for the healthy growth of children and teenagers.

Pastic packaging bags should have the protection function, convenience function, promotion function, security function and so on. Apart from that, the selected material needs to be environmental, convenient to draw and so on. The most commonly used packaging materials for food packaging are paper materials and cardboards. Paper materials are mainly coated paper, offset paper, and kraft paper; cardboard are mainly white cardboard, cream-colored cardboard, rice, and corrugated board. The basic raw material of paper is natural fiber. It is made into paper by pulping, modulation, paper making, processing. In order to improve the whiteness of the paper, most of the papers in the market are dealt with fluorescent brightener. Fluorescent whitening agent is a chemical material with strong carcinogenicity, which is poison to the human body.

Manufacturers should use paper without whiting in food packaging and paper tableware. However, due to lack of effective supervision, that whitening papers are used for food packaging are still common. There are also not clean raw material be used for production of food packaging paper, with heavy metals, pesticide residues and other pollution problems. Even reclaimed waste papers are used as raw material, causing chemical material pollution and microbiological pollution, indirectly causing harm to human health.

"The chilled sector will continue to increase its share of the overall market," predicts Jonathan Thomas, senior analyst with Leatherhead Food International. "And there will be increased competition from the food service sector, with a growing variety of home meal replacement solutions." Packaging can also differentiate one brand of product from another brand.

Product packaging is the continuation of commodity production. For example, food packaging bags is the continuation of food. Every product that needs packaging would finish its production process only after packaging. And then the product can be circulated and consumed, which achieve its value. This is because the packaging is the important measure to protect the integrity of goods in circulation. Some commodities live with packaging such as aluminum bags food packaging, and packaging becomes an integral whole with goods.

Thus, in order to live a healthier life, green sustainable packaging such as anti static bubble bags is produced.

Specific factors for sustainable design of packaging may include:
1. Use of minimal materials – reduced packaging, reduced layers of packaging, lower mass, etc.
2. Logistics efficiency – cube utilization, tare weight, enablement of efficient transportation, etc.
3. Energy efficiency, total energy content and usage, use of renewable energy, etc.
4. Recycled content – as available and functional.
5. Recyclability – recovery value, use of materials which are frequently and easily recycled.
6. Use of renewable resources in packaging.
7. Use of biodegradable materials – when appropriate and do not cause contamination of the recycling stream
8. Avoid the use of materials toxic to humans or the environment
9. Effects on atmosphere/climate – ozone layer, greenhouse gases (carbon dioxide and methane), 10.volatile organic compounds, etc.

The process of engineering more environmentally acceptable packages can include consideration of the costs. Some companies claim that their environmental packaging program is cost effective. Some alternative materials that are recycled/recyclable and/or less damaging to the environment can lead to companies incurring increased costs. There may be an expensive and lengthy process before the new forms of packaging are deemed safe to the public, and approval may take up to two years. It is important to note here, that for most of the developed world, tightening legislation, and changes in major retailer demand, the question is no longer "if" products and packaging should become more sustainable, but how-to and how-soon to do it.

The development of packaging materials and packaging process is never-ending. Some traditional packaging materials and packaging containers were replaced by a new materials and containers; this is the necessity of technology development and market competition. Safe and aseptic packaging's stable growth has been the public's expectations.

The food packaging bags, especially those are in direct contact with food, have the decisive effect to the stability of food, thus the applicability of the material will also directly affect the quality of food. Inappropriate material can cause migration, absorption and adsorption of active ingredients, and finally result in food poison. Therefore, before choosing container material for any food products, the intended use must be inspected and confirmed whether it is suitable for the food or not, such as the type shape coffee packaging. And its effect on the stability of the food must be fully evaluated.

Aseptic packaging refers to the packaging method which adopts the technology of instantaneous ultra high temperature sterilization to sterilize and pack the food product in "sterile" environment. It is better to keep food fresh, prolong the shelf life, save energy, reduce the packaging cost, and easy to realize the advantages of environmental protection packaging.

Absolute aseptic is impossible in any process of food production and packaging. Using antibacterial polymer packaging materials for food packaging can inhibit the contamination from bacterial, extend the shelf life and ensure food safety. Therefore, aseptic packaging will be the overall direction of food packaging.

Although the asepsis packing is mainly used in liquid milk and non-carbonated drinks market, but with the development of aseptic technique and the improvement of residents' disposable income, the scope of application of aseptic packaging will be more and more widely, especially in the field which the health standard is very strict, such as water, tea drinks, soup, wine, etc.

The plastic packaging bags are essential in preventing the goods from being damaged until the commodities are finally sent to customers' house, and they are inexpensive. They not only serve as the containers but also the right-hand helpers that bring people convenience. The packaging is particularly important when it comes to food protection, since the food products are easier to be damaged from outside force and they will spoil if not be well preserved. Then is the plastic food packaging bags qualified to protect the food products?

Although the glass or aluminum packages are more substantial in preventing the food from being damaged, plastic bags present more handiness and portability. We often packed the food with other devices such as refrigerator, to remove the air out of bags and prevent dust or moist that keep the food fresh, in this case, plastic bags are good preservers. What more, innovations in plastic technology have made it possible to shape the plastic packaging to suit the contours of a product so that it is more visible to the consumer. Except for its convenience, plastic packaging can protect the food against contamination, weather damage, scratched, deformation, corrosion and breaking. Plastic packaging keeps out moisture. This feature of plastic packaging is one reason why it finds favor for food packaging. Food spoils on exposure to water, and water-resistant plastic packaging helps prevent this.  

There is a long distance from the factories to where people live, during which the products may be damaged by unknown factors, and matters will become worse that if the products are made of glass or expensive crystal. Under this circumstance, bubble wrap, inflated bags and foam are good protective cushions during transportation, which can reduce the shock and prevent goods from bumping into hard objects or corners. The most simple and used plastic packaging materials for shipped goods are packaging peanuts and bubble wrap.

Apart from the food products, electronic products can also keep safe in plastics--anti static plastic bags, and the safety cannot be guaranteed in metal or glass packages.

Packing is designed to capture a customer's attention and it can directly effect whether they buy the product or not. Innovation and creativity come into play when it comes to packaging. A well-marketed product is packaged in a way that compels the customer to pick it up and take a closer look, at which point product descriptions and graphics must be clear.

Packaging especially food packaging bags, customer would like to pay more attention to the packaging pictures. If the pictures on the packaging look very delicious and tasted, most people would like to buy it. Proper packaging is a very important influence in consumer purchasing decisions. Although the most important function of packaging is to minimize product damage, color schematics are essential since a product must be visually appealing to garner consumer attention. The company name should also be visible on an effective package, particularly when good product branding has created consumer trust in the company. Packaging such as plastic packaging bags anti static bubble bags also include quantifiable product information, some of which can be required by law such as expiration dates.

Retailers and food manufacturers are working more closely than ever to create products designed for contemporary lifestyles, based on the latest technology. Likewise, packaging is of great importance in the final choice the consumer will make, because it directly involves convenience, appeal, information and branding. "In a very broad sense, the food industry is discovering the food service channel as a new distribution alternative. Alliances between food producers and food service operators will be the only means to develop successful solutions," said Axler.

"The chilled sector will continue to increase its share of the overall market," predicts Jonathan Thomas, senior analyst with Leatherhead Food International. "And there will be increased competition from the food service sector, with a growing variety of home meal replacement solutions." Packaging can also differentiate one brand of product from another brand. Because the product packaging can contain company names, logos and the color scheme of the company, it helps consumers to identify the product as it sits among the competition’s products on store shelves. For example, as a shopper walks through the coffee aisle of the local grocery store, the bright orange, pink and white packaging of the Dunkin’ Donuts coffee brand may be easily recognizable for the consumer to grab on his way by the coffee shelf. The shopper may identify with the company brand, which propels them to buy the product. If the product packaging changes, it may alter the brand perception of the company, which doesn’t mean that the consumer would not still purchase the product, but it may delay the purchase until the person is able to identify the product according to its new packaging.

With the increased importance placed on self-service marketing, the role of packaging is becoming quite significant. The Common uses of packaging include: protection, transmission, marketing, convenience, barrier protection and security. Even though the consumer is not dissatisfied with the packaging available on the market—such as anti static plastic bags , he would still like to be tempted by functional and attractive packaging ideas, by multisensory appeal and creative design - preferably with packaging ideas made from board. Good starting points for improvements, changes, innovations which optimize the features of packaging that determine buying decisions and thus generate new market potential can be summarized in consumers' top 3 requests about product packaging:

1. Eye-catching appearance.
What would you look firstly when you want to buy some snacks? Of course you will look the food packaging bags. A distinctive, unmistakable and eye-catching appearance is a signal at the POS to which all consumers and particularly the younger ones respond positively. Whatever stands out clearly in the monotonous competitive environment, whatever is surprising scores points with the consumer. Special effort makes a special impression - and is allowed to cost more too.

2. Design, shape and color.
The purpose of well-considered design, creative printing and finishing is to entice the consumer to devote attention to the pack and its contents at the POS. Aesthetics and attractiveness are major distinctive features - and are in fact essential in some product segments: beautiful packaging design is of central importance in the cosmetics and confectionery product groups. Consumers like to buy agreeably designed and decorative products!

3. Functionality.
Functional aspects are the basis for all successful packaging and for thus greater product success too. Product and aroma protection, hygiene and tightness, environmental responsibility and practical handling (in both use and storage) are just as important here as ideas that improve comfort: closure mechanisms, portioning, see-through windows.

The protective function of packaging essentially involves protecting the contents from the environment and vice versa. The inward protective function is intended to ensure full retention of the utility value of the packaged goods. The packaging is thus intended to protect the goods from loss, damage and theft. In addition, packaging must also reliably be able to withstand the many different static and dynamic forces to which it is subjected during transport, handling and storage operations. The goods frequently also require protection from climatic conditions, such as temperature, humidity, precipitation and solar radiation, which may require "inward packaging measures" in addition to any "outward packaging measures".
