Want to buy a suitable shrinking machine, we must first understand some basic knowledge of heat shrink packaging machine, the five major trends of heat shrink packaging machine, the following McGee Xiaobian for you to introduce the following.
Shrink packaging is a very popular product packaging equipment. The so-called shrinking machine uses a shrink film to wrap the product and then heat it until the shrink film is tightly wrapped around the product. The packaged product is not only economical but also environmentally friendly. It can also fully reflect the appearance of the product.
Packaging material for shrink packaging machine:
Shrink film is one of the most important materials in shrink packaging materials. According to the property that the thermoplastic material recovers under heating conditions, in the process of forming a film from a plastic raw material, it is previously heated and stretched, and cooled to form a shrink film. The manufacturing method includes a secondary stretching method in which a sheet-like film is formed, and then stretching in the longitudinal axis and the horizontal axis direction, and a simultaneous stretching in two directions at the same time, or a cylindrical stretching or a secondary stretching. A method of stretching once.
At present, most of the shrink film materials are: polyvinyl chloride, polyethylene and polypropylene, followed by vinylidene chloride, polyester, polystyrene, chlorinated rubber film and nylon resin, all of which are degradable. Environmentally friendly features.
The packaging form of the shrinking machine has now occupied a great position in the commodity market, and the goods after being packaged by it are also favored by a large number of consumers, and become a packaging device which is beautiful, fashionable and practical.
