Application field:
1. Composite film of alternative structure
Functional co -squeezing membranes can be used to replace the composite film of part of the structure. For example, the composite film of PA/PE in the middle layer can be replaced by PA/PE. Especially for products with high obstruction requirements such as fruit juice, tomato sauce, jelly, etc., the use of functional co -squeezing membranes can be used to effectively prevent problems such as discoloration and taste of products.
2. Used for automatic packaging machine
The common structure of functional co -squeezing films used under the automatic packaging machine is first. First, the supporting application of functional co -squeeze and automatic packaging machine can effectively reduce the labor intensity of manual packaging. This is equivalent to using the labor intensity of 15 to 20 manufacturers when it is packed by manual packaging, which not only relieves the problem of recruitment difficulties, but also reduces the cost of employment.
Secondly, the functional co -squeezing film can achieve automatic filling on the automatic packaging machine, which effectively reduces the secondary pollution caused by the manual packaging of products with high hygiene requirements such as food and drugs.
Furthermore, the functional co -squeezing does not require a composite process, which can control the amount of organic solvents well, providing reliable guarantee for the safety and environmental protection of food, drugs and other products.
3. Cushion packaging for electronic appliances products
Functional co -squeezing membranes are used as a buffer packaging for electronic electrical products. It has very prominent advantages. The conventional structure is P E/PE/TIE/PA/TI E/PE/PE. This type of buffer packaging is also called "inflatable packaging". The film materials used must have good mechanical properties, such as puncture resistance, squeezing, good resistance, oil resistance, light resistance, etc. Performance polymer granules are combined to achieve.
4. Used as an infusion bag
Functional co -squeezing film is the main application material in the current infusion bag market. In the past, it was basically imported. In recent years, some domestic material manufacturers have also actively actively developed. Squeeze the film.
This type of function -type co -squeezing film is a variety of polymer granules with special functions. Mixed with a certain proportion. Under the appropriate conditions, these mixed granules are squeezed out of the extruder. Cold for cooling. In the process of extruding out, some polymer granules also need to pass the cross -linking effect through ray radiation. The air cleansing level of this type of functional co -squeezing film production workshop must reach 100 levels, so as to ensure the cleanliness and asepticity of the functional co -squeezing surface surface, so that the physical and chemical indicators of the infusion bags meet the medical requirements.
The advantages of functional co -squeezing infusion bags are as follows:
① Under the effect of the air pressure of the infusion bag, it is self -discharged;
② Not only to prevent the pollution of the return air, but also the problem of slight leakage of the soft bag; ③ In the case of unable to automatically infusion, the infusion function can be restored by external pressure.
5. Used as a vacuum packaging bag
The packaging of aquatic products, seafood, rice, and other products needs to meet the requirements of puncture tolerance and anti -falling. The real -scale packaging bag made of functional co -squeezing membranes can be used to meet the above needs by adjusting the proportion of polymers. The advantages that cannot be compared, the conventional structure is: PA/TIE/PE/TIE/PA/TIE/PE/PE/PE (EVA), which has high strength; PA/TIE/PE/TIE/EVOH/PE/PE/PE /PE (EVA), with high strength, high resistance. In the future, the functional co -squeezing film will play a greater role in the vacuum packaging bag market.
