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.

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.

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.

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".
