A large number of multi-functional composite films have been developed abroad to further refine their functions. For example: cold-resistant film can withstand -18 ° C, -20 ° C, -35 ° C low temperature environment; moisture-proof film made of moisture-proof treatment of PP, its series of products can be divided into moisture-proof, anti-condensation, anti-cooling, adjustable moisture Several types; anti-corrosion film can package perishable, acidity, sweetness of food; friction film stacking stability; special PE film resistant to chemicals, corrosion; odor-free film added odor-free insecticide; The heat-resistant film of nylon 66 replaces the biaxially stretched nylon 6 packaged food, which has a high temperature resistance up to 140 ° C; the new special food packaging film can improve the aroma of the food packaging; the amorphous nylon film has transparency similar to glass; the high shielding film can protect Color, aroma, taste, nutritional index and stability of taste quality; metal protective film is packaged with LDPE modified film for liquid product, which can be heat-sealed in low temperature environment; PP synthetic paper is used to improve the light resistance, cold resistance and resistance of the package. Heat, water resistance, moisture resistance, grease resistance, acid resistance, alkali resistance and impact resistance.
At present, foreign popular plastic cups, composite cups (outer layer PSP, inner layer PP, cover PS) package cold, hot drinks, wine, convenience foods. France uses PE bottles to package fructose and yogurt, and Germany uses PC bottles to pack milk. China uses PE bottles to package medicines.
Black Wire
Black annealed wire, which is made of low carbon steel or iron, is often applied for weaving, baling in home use and construction. For example, baling hay in agriculture area.
Black annealed wire is mainly processed into coil wire, spool wire or big package wire. Or further straightened and cut into cut wire and U type wire. Compared with black Iron Wire, black annealed wire is more softer and has higher flexibility.
