Application of stretched film

The main uses of stretching thin currently include the following

1) Sales packaging of fresh food

2) Storage and packaging of fish, meat, fruits, and vegetables

3) Packaging of frozen food

4) Bundling and packaging of goods.

5) Wrapping packaging for freight pallets.

6) Sealing film for experimental vessels, etc

Wrapping fruits and vegetables with stretchable cling film has the effect of delaying their metabolism rate, preventing water evaporation, and isolating diseases and pests. For example, citrus fruits treated with conventional drugs are individually packaged with PE cling film and stored for 3 months. The fruits remain fresh and full, with unchanged original flavor and a loss rate of only 4.85%; Fresh meat and fish wrapped in stretched cling film can preserve the hemoglobin in the meat and fish. Although stored for a long time, the fresh meat still appears bright red; Frozen food wrapped in stretched cling film can not only maintain the original flavor of the food, prevent the drying of frozen food, but also reduce the fishy smell of fresh food in the refrigerator, and avoid cross flavors between various foods.

The stretching and winding performance of stretched films utilizes the elastic stretching ability of the film at room temperature, namely the elastic recovery effect. The packaging of the goods can be either full width or rotary wrapped. The stretch winding film can be used for small packages of hardware and electrical appliances, instruments and meters, Machine element, glass enamel, paper, cardboard, cloth, clothing and other commodities, and large packages such as trays. It has the advantages of moisture-proof, dust-proof, clean and beautiful. Compared to shrink film packaging, the effect is the same. The Lazhong film does not require heating and baking treatment, which saves energy and does not affect the wrapping elasticity at low temperatures.

By utilizing the self-adhesiveness of the stretched film, sticking the stretched film to the mouth of experimental vessels (such as test tubes, ovens, wide mouthed bottles, etc.) can play a sealing role. The use of stretched film has the advantages of easy adhesion and easy removal. Stretch sealing film can not only prevent dust and maintain cleanliness inside experimental vessels, but also prevent the volatilization of reagents, ensure the accuracy of experiments, prevent various harmful gases from polluting the laboratory, and also protect the surfaces of furniture, instruments, and meters.
