1. High precision alloy steel die head make sure the customer can get the best coating effection.
2. Total Machine is controlled by PLC.Precision control coating speed and glue amount.
3. Increase the film function in some glue or substrate is not suitable for direct knife coating that realize 2 kinds of craftwork (knife coating and film coating.) on one machine.
1, release film
A release film refers to a film having a separation surface which is not sticky or slightly viscous after contact with a specific material under limited conditions.
Usually, in order to increase the release force of the plastic film, the plastic film is subjected to plasma treatment, or fluorine treatment, or a silicon release agent is applied on the surface of the film material, so that it exhibits for various pressure sensitive adhesives. Extremely light and stable release force. According to the different release force of the release film, the viscosity of the insulation product is different, and the release force is adjusted accordingly, so that it achieves extremely light and stable release force during peeling.
• 1.2 release film classification by substrate:
> PE (polyethylene) release film;
> BOPP (polypropylene) release film;
> PET (polyester) release film.
Classified by release force:
>Ultra-light release liner (<5§)
>Light release release film (5-10g);
> Medium release release film (10-50g);
>Removal release film (50g or more).
Classified by silicone oil coating:
>Ordinary silicone oil release film >Fluorine plastic release film
>Other categories: such as high temperature silicone pressure sensitive adhesive.
Classified by surface color:
A red release film, a yellow release film, a green release film, a blue release film, a white release film, and the like, and a PET release film of various colors.
Classification by substrate surface treatment:
Single-sided release film, double-sided release film, no-free release film.
(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.
