What are the characteristics and uses of PET transfer film?
PET transfer film, in some industries into transfer paper, in fact, its material is plastic film.
PET transfer film belongs to the classification of PET release film. It is mainly used to transfer words and patterns on other films or stickers to the surface of another item, while PET transfer film plays a temporary role of carrying, transfer film is also called thermal transfer film. This kind of transfer film is characterized by high tensile strength, good thermal stability, low thermal shrinkage rate, smooth and smooth surface, good peeling property, and can be used repeatedly.
It is mainly used as the carrier of vacuum aluminizing, that is, the PET film is placed in the vacuum aluminizing machine after aluminizing, the glue is compounded with the paper, and then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the cardboard through the adhesive effect, form the so-called aluminized cardboard.
The production process of aluminum-plated cardboard is: PET base film → release layer → color layer → aluminum layer → glue layer → transfer to cardboard.
Vacuum aluminized cardboard is a kind of cardboard with metallic luster, which is an advanced and novel packaging material developed in recent years.
This kind of aluminum-plated cardboard is bright in color, strong in metallic sense, and the printing is bright and elegant. It can replace the large-area bronzing of the printed matter and play a role in the beautification of the goods.
Because it adopts vacuum aluminizing method, it only covers a layer of 0. 25um ~ 0.
The thin, tight and bright aluminum layer of 3um is only 1/500 of the aluminum cardboard aluminum foil layer, so it has not only noble and beautiful metal texture, but also degradable and recyclable environmental protection attributes, it is a green packaging material.
