The key to the problem of wasting resources, losing economy, and polluting the environment in supermarket shopping bags is not the plastic itself, but more importantly, how to achieve timely and scientific recycling, utilization, and pollution-free treatment of plastic bags after use, and turn waste into treasure! On the one hand, strengthen governance, such as setting up recycling outlets (the recycling rate of waste plastic recycling in China is only 10%, much lower than the developed level), establishing the whole process management of waste plastic bag recycling, transportation, storage and reuse, so as to promote the recycling of waste plastic bags.
Plastic bags are a commonly used item in our daily lives, and are widely used due to their advantages of being cheap, lightweight, large capacity, and easy to store. Especially now many manufacturers will customize a plastic bag packaging for their products. But many customers who first order plastic packaging bags do not understand the material of plastic packaging bags. What are the advantages of these plastic packaging bag materials?
1. Biaxially stretched polypropylene BOPP: high transparency, tensile resistance, cold resistance, heat resistance, -40 ° C -120 ° C;
2. Biaxially stretched polypropylene extinction film: a thin film with low reflectivity and a semi transparent shape, which has a extinction effect;
3. Cast polypropylene CPP: Good gloss, good transparency, and heat sealing properties. Cast high-temperature film is suitable for steaming and packaging in plastic packaging;
4. Polyethylene PE: Transparent, with good gloss, heat sealing, and cold resistance;
5. Polyester film PET: It has tensile resistance, heat resistance of 60-150 degrees, good airtightness, suitable for cooking, and no heat sealing;
6. Nylon PA or NY: colorless, high transparency, cold resistant, heat resistant, oil resistant, and can be steamed. Easy to absorb moisture, without heat sealing properties.
The above are some common materials for plastic packaging bags and their characteristics. But on finished plastic packaging bags, they are all composed of multiple composite materials. Different combinations have different adaptability to different occasions. So when you order plastic bags first, you need to understand the characteristics of the materials in order to choose the right one.
