It's be mainly used for bopp film gelatinizing producing，The tape is mainly used to seal the box, seal the cover and bind the articles, and can also be used as office supplies.
Second, the length of the coating section changes, the spacing is unstable:
1. The length of the segment changes greatly (* is shortened) * The variation of the pitch is small (narrowed)
2) The gap between the back roller and the rubber roller is too small and too tight.
3) The tension before and after the mismatch, the unwinding is greater than the winding solution
1) Cleaning roller
2) Adjust the diagonal block to a fixed position
3) Adjust with reference to setting parameters
2. The length of the segment changes greatly (* becomes shorter). The pitch changes greatly (larger).
If the length of the head of the pole piece and the head of the next piece are changed greatly (smaller), the tail change between the two pieces of the pole piece is small, so that the solenoid valve (control roller movement) is inflexible.
3. The length of the segment changes greatly (* becomes longer) * The pitch changes greatly (widening)
1) The surface of the back roller and the rear rubber roller are not clean.
2) There is no pinch roller, there may be no pinch or out of control
3) The tension before and after does not match, the winding is larger than the unwinding solution
1) Cleaning roller
2) Increase the pinch roller
3) Adjust with reference to the setting parameters. 1) The surface of the back roller and the rear rubber roller are not clean.
(2) PET transfer film
The transfer film is also called a heat transfer film. The transfer film is characterized by high tensile strength, good thermal stability, low heat shrinkage, smooth surface and good peelability, and can be used repeatedly. It is mainly used as a vacuum aluminum plating carrier. After the PET film is placed in a vacuum aluminum plating machine, the rubber film is combined with the paper, and then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the paperboard by the adhesive action. A so-called aluminized cardboard is formed. The production process of aluminized cardboard is:
PET base film→release layer→color layer→aluminized layer→glue layer→transfer to cardboard.
Vacuum aluminum-plated cardboard is a kind of high-grade novel packaging material developed with metal-gloss cardboard. This kind of aluminum-plated cardboard has bright color, strong metallic feeling, bright and elegant printing, and can replace the large-area bronzing of printed matter, which has played a icing on the cake for the beautification of goods. Because it adopts the vacuum aluminum plating method, the surface of the cardboard is covered with only a thin layer of 0.25um~0.3um thin and bright and bright, only one-fifth of the aluminum foil layer of the aluminum foil, so that it It has a noble and beautiful metallic texture, and has environmentally friendly properties that are degradable and recyclable. It is a green packaging material. Through the formulation and process adjustment, Jiangsu Zhongda was successfully developed in 2005 and put into the market in large quantities, receiving good economic benefits.
