In the packaging industry, stretch film must be not strange. The so-called stretch film is also called thermoforming film. It has high flexibility, not easy to break, strong anti-blasting force, strong impact resistance, strong tear resistance, and strong tensile force,which can replace box packaging. Because of the various advantages of stretched film, its development prospects are also optimistic in the industry.At present, there are many types of stretched films on the market, and manufacturers of stretched films have sprung up.
Jiangsu Sunkey Packaging has specialized in producing stretch film for more than ten years. The company has a 100,000-level clean production workshop and automated large-scale production process.

As a professional stretch film manufacturer, we have summarized several common problems often encountered in the daily customized production of stretch films and its corresponding treatment methods:
Problem one: after boiling and sterilization, the packing is not good and the curl heavily.
Solution: Change the structure and extend the stretch molding time.
Problem two: difficult to tear, which causes inconvenience during normal consumption.
Solution: Use cast film, reduce nylon percentage, change materials.
Problem three: The packaging material does not fit tightly with the contents, and the inside contents can move.
Solution: The mold does not match the contents and the vacuum degree is not enough.
Problem four: During the shelf life, oily food is released or food with high moisture content is lost.
Solution: increase the thickness of the material or change the type of packaging material to improve the barrier performance of the material.
Problem five: Film break during stretching.
Solution: Adjust the preheating and molding temperature, and check whether the stretched air pressure is normal.
Problem six: The film is slightly narrow and cannot be used normally on an automatic packaging machine. It should be noted that in order to save costs, customers will provide product lower deviations to manufacturer, such as: 422mm wide equipment,customer asked for 420mm wide specifications.
Solution: To make it clear the width of the customer’s equipment. If the above situation occurs, please explain to the customer, when place order, there should be no lower deviation.
