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.
