Commonly used plastic film include polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), polyester film (PET), polypropylene (PP), nylon, etc. The performance of various plastic film is different, and the degree of difficulty in printing is also different, and the use of packaging materials is also different.
Polyethylene film is a colorless, odorless, odorless, translucent insulating material, which is used as a packaging bag; food bags can also make various containers. It is an inert material, so it is more difficult to print. It must be printed after processing.
The optical resistance and aging resistance of the polyvinyl chloride booking membrane are better and have better tear resistance. It can breathe. It is a clean, colorless and transparent film. Generally, plasticizers are added. It is soluble in acetone , Circle Alcheon and other solvents. Therefore, ink made of polyvinyl chloride resin can be printed. Suitable for packaging bags, book skin, etc.
The polystyrene film is a soft and tough film, clean, colorless and transparent. When the plasticizer is not contained, the membrane layer is soft, frozen, and does not aging. The fastness is better.
Polyester film is colorless, transparent, humid -resistant, impermeable, soft, strong, acid -alkali -resistant oil ester and solvents, and not afraid of high and low temperature. Essence Used for packaging and composite materials.
The polypropylene film has a good gloss and good transparency. The heat -resistant acid and alkali, solvents, friction resistance, tear resistance, breathable, and cannot be sealed when below 160 ° C.
The strength of the nylon film is larger than the polyethylene film. It has odorless, non -transparent bacteria, oil -resistant, ester, boiling water and most solvents. It is generally used in loads, wear -resistant packaging, and cooking packaging (the heat of food). It does not The surface treatment is required to print.
Polyethylene molecules basically do not have polar groups. It is a non -polar printed high score. The polypropylene molecule contains a base. It also belongs to non -polar high molecules. Therefore, their affinity with inks is poor, so it must be obtained before printing before printing before printing.
Most of the treatment methods are oxidized to increase the polarity and change the surface structure. Specific treatment methods include discharge (commonly known as electric halo, electric spark) method, flame method, ultraviolet radiation method, acid (sulfuric acid, chromic acid) treatment method. The discharge method is relatively simple and popular.
