Cheese packaging bags
PE polyethylene: The main component is polyethylene resin, with a small amount of lubricants, aging agents, and other additives added. Polyethylene is a odorless, non-toxic, and milky white waxy solid. The surface gloss and transparency of the packaging bag produced are not high. Good plasticity.
1. Good barrier performance: effectively prevents the immersion of water and moisture, but the air barrier performance is not very good.
2. Strong chemical stability: At room temperature, it does not react with acids or alkalis, but has poor oil resistance.
3. Mechanical properties: Good tensile strength, tear strength, and flexibility.
4. High and low temperature resistance: It has good low temperature resistance and can be used for food refrigeration, but its high temperature resistance is poor and cannot be cooked at high temperatures frequently.
5. Health and safety: Meet food safety standards and can come into direct contact with food.
PP Polypropylene: The main component is polypropylene resin, with high glossiness and transparency. Its heat sealing performance is worse than that of PE, but it is superior to other plastic materials.
1. The barrier performance is better than PE, and the strength, hardness, and rigidity are higher than PE;
2. Health and safety are higher than PE
3. It has excellent high-temperature resistance and can be used for a long time at temperatures ranging from 100 to 200 degrees Celsius, but its low-temperature resistance is worse than PE, and its performance becomes brittle when it reaches -17 degrees Celsius.
