The main applications of stretch thinning are as follows
1) Sales packaging of fresh food
2) Storage packaging for fish, meat, fruits, and vegetables
3) Packaging of frozen food
4) The bundling and packaging of goods.
5) Wrapping packaging of freight pallets.
6) Sealing film for experimental vessels, etc
Wrapping fruits and vegetables with stretch cling film has the effect of slowing down the metabolism rate of fruits and vegetables, preventing water evaporation, and isolating pests and diseases. For example, citrus fruits treated with conventional drugs can be individually packaged with PE cling film and stored for 3 months. The fruits are still fresh and full, with the original flavor unchanged and a loss rate of only 4.85%; Fresh meat and fish wrapped in stretch wrap can preserve the hemoglobin in them. Even after long-term storage, the fresh meat still appears bright red; Frozen food wrapped in stretch wrap can not only maintain the original flavor of the food, prevent it from drying out, but also reduce the fishy and odorous taste of fresh food in the refrigerator, avoiding cross contamination between various foods.
The stretch winding performance of stretch film is based on the elastic stretching ability of the film at room temperature, namely the elastic recovery effect. The packaging of the goods can be done as a whole package or a rotating wrap package. Stretch wrap film can be used for small packaging of hardware and electrical appliances, instruments and meters, mechanical parts, glass enamel, paper, cardboard, cloth, clothing and other products, as well as large packaging such as pallets. It has the advantages of moisture resistance, dust prevention, cleanliness, and aesthetics. Compared to shrink film packaging, the effect is the same. Lazhong film does not require heating and baking treatment, saving energy, and its elasticity is not affected when wrapped at low temperatures.
By utilizing the self-adhesive properties of stretch film, it can be used to seal the mouth of experimental vessels such as test tubes, preforms, wide mouthed bottles, etc. The use of stretch film has the advantages of easy adhesion and tear off. Stretch sealing film can not only prevent dust and maintain the cleanliness of experimental vessels, but also prevent the evaporation of reagents, ensure the accuracy of experiments, prevent various harmful gases from contaminating the laboratory, and protect the surfaces of furniture, instruments, and meters.
