Applicable products for sterile liquid packaging bags..stand up pouch with spout packaging

The production process of sterile packaging bags is mainly divided into film blowing, cutting, heat sealing, vacuum packaging, and sterilization.

Blowing film: Open the air purification system in the workshop and disinfect the workshop and operators to ensure that the operating environment meets the set standards. Blow film the purified polyethylene particles within the specified temperature range.

Cutting: The tubular film after blowing is cut into different sizes of film cylinders according to customer requirements.

Heat sealing bag making: Use a heat sealing machine to seal the membrane cylinder.

Vacuum packaging: After sealing, carry out multi-layer vacuum packaging according to the specified quantity.

Sterilization: Sterilize the packaged bags with gamma rays to meet the product's sterility requirements.

The delamination phenomenon of sterile packaging bags is mainly caused by improper production process processing. For example, improper handling of ink, glue, film, etc. may cause delamination of the finished steaming bag during use.

The common application of elastic and easy to cover film in the production process of ink/glue operation is jelly covering film. Improper use of ink/glue can cause delamination of sterile packaging bags. For example, if the amount of curing agent does not meet the requirements, if the amount is too low, it will lead to insufficient crosslinking degree and a decrease in adhesive strength; When the dosage is too high, it affects the crystallization of polymer materials, causing excessive shrinkage of the ink layer and causing delamination. Alternatively, during the production of sterile packaging bags, the aging time is not sufficient, resulting in poor cross-linking and insufficient water solubility of the ink layer.
