Pre-coated film lamination and Instant film lamination

The pre-coating film refers to a process in which a plastic film is sized and re-rolled before being combined with a paper printed product. It is firstly applied to the film by the pre-coated film processing factory according to the size of the specification. The glue is applied to the film for re-rolling, and then combined with the printed matter.

The pre-coated film was first used in 1989 and has been widely used in Europe and the United States. It entered Asia around 1996. At the same time as entering Asia, Europe and the United States have announced that it is forbidden to use the film as a pre-coating film. Due to the late use, all the countries in Asia except Japan have used pre-coated films, and other countries (such as China, South Korea, etc.) are in the state of pre-coating and film coating.【Roll Laminator Manufacturers】China has only used pre-coated films since 2000, and the market share of pre-coated films in China is still small. Precoat films have many advantages over instant coatings. If the pollution is reduced, there is no damage to the human body; the quality of the film will not be affected by the different properties of the paper or the color of the ink; the pre-coating film laminating machine is simpler to operate, and the processed image is better; the wrinkles are basically eliminated. , bubbles, shedding and other phenomena. Most notably, this is an environmentally friendly process, and the entire production process is harmless to the human body.

However, the promotion of pre-coated film in China is still relatively slow. Among them, the cost issue is a big influential factor, which determines the enthusiasm of investors for the pre-coating process. 【Reel to Reel Lamination Machine】In a recent survey, more than half of the respondents believe that pre-coated products are expensive in terms of price, because pre-coated products are printing consumables, and the cost of printing is a non-negligible problem for printers when selecting consumables. . In addition, due to the lack of paper and film separation technology in China, pre-coated films cannot be completely called an environmentally friendly process in China. In response to this situation, pre-coated products should reduce costs through mass production, so that market prices are getting closer to the needs of printers. At the same time, the research and development or introduction of the paper membrane separation technology should also attract the attention of relevant departments, in order to achieve environmentally friendly coating and rational development of the laminating process without being able to discard the laminating process.【Laminating Machine Supplier】It is a brand-new transfer technology that can cope with complex workpieces and is suitable for different materials.

Basic Knowledge for Thermal Film Laminating Machine

The pre-coating film lamination is less polluted than the instant coating film lamination and has no harm to the human body. There is no difference in the nature of the paper and it affects the quality. There is no difference in ink color and it affects the filming effect. There is no effect of using adhesives with vinyl binding. The pre-coated film laminating machine is easy to handle and easy to process.【 Thermal Laminator 】The processed graphics are more beautiful and have a good effect. Basically eliminate wrinkles, bubbles, shedding and so on. It has a wide range of applications and can be used for film processing other than printing.


The pre-coating film refers to a process in which a plastic film is sized and re-rolled before being combined with a paper printed product. It is firstly applied to the film by the pre-coated film processing factory according to the size of the specification. The glue is applied to the film for re-rolling, and then combined with the printed matter.【 Lamination Machine Manufacturer 】The film, that is, the film, is a processing technique in which a plastic film is coated with a binder and the paper print is heated and pressurized to bond it together to form a paper-plastic product. The film-coated printed matter has a thin and transparent plastic film on the surface, and the surface is smoother and brighter, thereby improving the gloss and fastness of the printed matter. The color of the graphic is more vivid, three-dimensional, and waterproof. Anti-fouling, abrasion resistance, folding resistance, chemical corrosion resistance, etc.


The pre-coated film is composed of a substrate and a binder layer, and the substrate is usually a polyester (PET) film and a biaxially oriented polypropylene (BOPP) film. BOPP film has the characteristics of high transparency, good brightness, non-toxic and tasteless, water resistance, heat resistance, low cost and soft texture. It is an ideal material in the film coating process, and its thickness is about 12-20um. Therefore, the material cost From the perspective of processing technology, most of the pre-coated film substrates use BOPP film.【Best Thermal Laminator Machine 】The adhesive layer of the pre-coated film has two types of melt type and solvent volatilization type. According to different processing equipment and process conditions, adhesive layers of different thicknesses are selected, and the thickness of the adhesive layer is generally between 5-15 um. At present, the adhesive layer of the domestic pre-coated film is mainly composed of hot melt adhesive or organic polymer low temperature resin. Hot melt adhesive is made by blending and modifying several main materials such as main adhesive resin, tackifier and conditioner. The organic polymer resin is a single polymer low temperature copolymer. Since the hot melt adhesive is a mixture of several materials, the transparency after coating is significantly lower than that of the low temperature pure resin type pre-coated.


The production process of the solvent volatilization type pre-coated film is similar to the film coating process, and the colloid is dissolved in an organic solvent and then coated on the film substrate, so that the organic solvent may be volatilized incompletely, and the odor may be generated during the film operation. 【 Film Lamination Machine 】The operator causes damage (relative to the coating film coating process, the damage is much smaller), etc., the solvent evaporates after the film is coated, and it is easy to form bubbles on the surface of the printed matter.

Why Bubble Appeared during the lamination process?

The cause of bubble formation:

Different types of composite substrates have different physical properties (such as gas permeability), and have a great relationship with the formation of composite film bubbles. Generally speaking, a substrate with good gas permeability (such as BOPP, CPP, CPE, LDPE) or a composite substrate with poor gas permeability (such as PVDC, BOPA) and another composite substrate with good gas permeability are compounded. It is not easy to generate bubbles. [ roll to roll lamination machine]

However, if the two substrates have poor gas permeability, when they are compounded, bubbles are easily generated, such as PVDC and BOPA. This is because the gas permeability of the two composite substrates is relatively poor, and the adhesive inevitably mixes a small amount of air on the compounding system. At the same time, the isocyanate adhesive itself is cross-linked and solidified during the curing stage of the composite film, and also produces gaseous by-products such as carbon dioxide (CO2). In this way, a large number of tiny bubbles are generated, thereby affecting the apparent quality of the composite film. [ film lamination machine]

At the same time, in order to make the composite substrate have a certain surface tension, the surface properties of the substrate must be treated, such as corona treatment, to improve the wettability of the surface of the composite substrate and improve the roughness, but the roughness exceeds At certain limits, it is difficult to be filled with viscous glue. Thus, large and small bubbles are formed between these minute engaging faces.
