Knowledge sharing and collection share on Packaging film industrial, such as stretch film, shrink film, silage film, protective film, to help collect useful information and avoid detours
Stretch wrap film is a deformation stress caused by mechanical stretching device or manual stretching of the film at room temperature. It is a packaging method for packaging and storage. This is a form of packaging that is very popular…
Stretch pallet film is a packaging method that uses mechanical stretching equipment or manual stretching of the film to force the deformation of the film at normal temperature to wrap the goods for easy transportation. It is a packaging method…
In order to reduce the environmental pollution damage and enhance the environmental protection in packaging, many manufacturers will choose to use cast film to package the product after the production of the product, so what functions and advantages does the…
This is a well-known proverb, such as industry. Industry is also an indispensable industry to promote social development, and products must be needed in the industry to promote the development of social life. , The production equipment of cast film…
Stretch film, also known as wrapping film, pallet film, has the characteristics of good stretch performance, tear resistance, strong penetration resistance, high transparency, good self-adhesion and high shrinkage rate, tight packaging, no looseness . It can be widely used in…
How much do you know about the stretching laws of stretched films? Stretch film is oriented at a certain temperature, usually above the glass transition temperature of the polymer, below the melting point of the polymer thick film or sheet…
Causes and solutions of poor stretch ability of stretched film Stretch film must have high puncture resistance, good shrinkage and certain shrinkage stress. During the shrinking process, the film cannot create holes. Since shrink film is often used outdoors, it…
– Is the viscosity of the stretched film insufficient? Is there a problem with the method of production?- Polyethylene can provide outstanding mechanical strength, excellent ductility, and better resilience for stretched films, but it cannot provide satisfactory external viscosity. Therefore,…
