Transfer film, also known as thermal transfer film, this transfer film is characterized by high tensile strength, good thermal stability, low heat shrinkage, surface smooth and clean, good peelability, can be repeatedly used.
Vacuum aluminum foil cardboard is a kind of metal luster cardboard, is developed in recent years, a kind of advanced new packaging materials. This bright aluminum plated cardboard, metallic strong, bright and elegant printed products, printing can replace the large area of gold foil, for the beautification of the product played a icing on the cake. Because it adopts the method of vacuum aluminizing, only a layer of 0.25um ~ 0.3um thin and tightly bright aluminum layer is covered on the surface of the paper jam, which is only one hundredth of one percent of the mounted aluminum foil paper layer, A noble and beautiful metal texture, but also has biodegradable, recyclable environmental properties, is a green packaging materials.
Nowadays, the world has entered the era of information. Electromagnetic waves of various frequencies and wavelengths fill the entire earth space. These electromagnetic waves may interfere with unshielded sensitive electronic components, circuit boards and communication equipment to varying degrees, causing data distortion. Communication disorder. The electromagnetic induction and friction generated by the static on a variety of sensitive components, instrumentation, some chemical products, as a result of electrostatic accumulation of packaging film high voltage discharge, the consequences will be destructive, so the development of anti-static PET packaging film is also very important. Anti-static film is characterized by the PET film by adding an antistatic agent, the film surface to form a very thin conductive layer, and the formation of a continuous phase, improve the surface conductivity, the resulting charge leakage as soon as possible. The anti-static film generally requires the surface resistivity ≤ 109 ~ 11 ohms.
Heat sealing film
Ordinary PET is a crystalline polymer, PET film after stretching orientation, will produce a greater degree of crystallization, such as its heat-sealing, it will produce shrinkage deformation, so the normal PET film does not have heat sealing performance. PET film is used as a commodity packaging, in order to solve the problem of heat sealing, usually BOPET film and PE film or CPP film composite method, which to some extent limits the BOPET film applications.
In order to solve the problem of heat sealing, three-layer co-extruded heat-sealable PET film has been developed by modifying the PET resin and using a three-layer A / B / C die. The heat-sealable PET film Because of the heat-sealable layer, it can be directly heat-sealed, easy to use.
Heat-sealable PET film can be widely used in a variety of commodity packaging and card protection film and other fields.
