Information

How to inspect the film before the operation of the laminating machine 1. Tear off one corner of the finished sample film in the width direction. The imprint is transferred to the film along with the fiber of the adhesive layer and paper, indicating that the printed matter is well bonded to the film and is a qualified product.
2. Put the coated sample into the drying tunnel and bake at 60-65 degrees Celsius for about 30 minutes. If there is no blistering, no delamination, no wrinkles, and it is a qualified product. After baking, the tear-off film should not be separated from the paper perfectly. 3. Soak the sample in cold water for 1 hour and take it out. If the plastic film does not separate from the printed matter, it is qualified. 4. Put the sample on the creasing machine and apply pressure. If the embossed part does not delaminate, it is a qualified product. After the coated samples have passed one or more inspection methods and meet the requirements, they can be put into mass production. If it does not meet the requirements, the sample is unqualified, and the process must be adjusted and tested again until the inspection is qualified. Laminator equipment operation process flow Laminator laminator is divided into two categories according to the equipment and process, one is "immediate coating", the other is "pre-coating", which is divided into two categories: light film and sub-film kind. Laminating process refers to the whole process of laminating pictures, papers, photos, etc. The coated products have high anti-corrosion, waterproof, dustproof, anti-wrinkle and anti-ultraviolet properties, which can produce a strong three-dimensional feeling and artistic appeal. . Let's take a look at the operation process of the laminating machine equipment: 1. Instant film laminating machine It is mainly composed of a coating film processing plant or a processing workshop. According to the needs, the roll plastic film is coated with an adhesive, dried (lightly) composited, and pressurized to adhere the paper film together to form a film-coated product. That is to say, the film coating equipment has two kinds of automatic and semi-automatic. The basic working principle is the same. The process flow mainly includes unwinding → sizing and coating → drying → compounding → slitting → finished product accumulation. 2. Pre-coating film laminating machine Pre-coating film is a process of rewinding the plastic film on the film cloth in advance, and then compounding it with the paper printing. The pre-coated film is made by the pre-coated film processing plant according to the different specifications and sizes used. The glue is first coated and rewinded for the user to choose, and then combined with the printed paper. There are currently three types of pre-coated films: instant thermal film, pressure-sensitive film and special film. The process flow is mainly pre-gluing → winding → sizing and coating (hanging type) → curing and cooling → rewinding → slitting → recovery Roll → finished product packaging. Pre-coating machine: temperature adjustment → winding → paper feeding → heating → compounding → slitting → automatic stacking → finished product.
