Color printing blister mask details

Color printing blister mask: The general name of the blister mask made by combining the two methods of blister (vacuum thermoforming) and color printing (offset printing or screen printing) with the corresponding mask mold.
The main advantages of color printing blister masks are light weight, convenient transportation, meeting the requirements of environmentally friendly green production masks; capable of producing any special-shaped products, easy to operate; the products produced can be freely changed in appearance, strong in three-dimensional sense, realistic in effect, style More, and suitable for mechanization, saving manpower and improving efficiency.
The main equipments required for color printing blister masks: color printing blister machine, screen printing machine, punching machine, punching machine, vacuum machine, transparent blister machine color printing blister mask process: plastic sheet – sheet fixing – heating – – Forming – demoulding – stripping edge – basic knowledge of finished color printing plastic raw materials:
1. PVC (polyvinyl chloride) and PVC alloy (PVC + ABS) sheet This product has high strength, good impact toughness, non-toxic and easy to plastic molding. It is mainly used in the construction industry for anti-acid and alkali protection panels, flooring, welding sink panels and various plastic products such as pet cage trays after plastic molding.
PVC boards can be further divided into: PVC hard boards, PVC soft boards and environmentally friendly PVC boards.
1PVC hard board, thickness: 1-25mm Maximum width: 1.5m This product has good corrosion resistance, high strength, high hardness, easy processing and welding, etc. It is widely used in acid and alkali pools, extraction vessels, and other chemicals. Water treatment, environmental protection equipment, etc. Transparent PVC hard board PVC transparent soft board: Thickness: 1-20mm Maximum width: 1.3m The product is non-toxic, hygienic, weather resistant, high strength, good transparency, physical properties better than plexiglass Widely used in equipment guards, drinking water tanks, liquid level display containers, etc.
2PVC soft board: thickness: 1-10mm maximum width: 1.3m The product is soft and wear-resistant, acid, alkali, corrosion resistant, good tear resistance, good solderability. Widely used in chemical, electroplating, lining of electrolytic cell , insulating mats, etc.
3 environmentally friendly PVC sheet, thickness: 1-20mm, specific gravity: 1.42-1.56 Color: light gray, white, etc. Features: high surface brightness, non-toxic, suitable for export quality requirements. PS (polystyrene) sheet, commonly known as plexiglass sheet or acrylic sheet. It has excellent tensile properties and has the characteristics of electrical conductivity, antistatic performance, non-toxicity and good impact resistance. It is widely used in the deep processing of plastic products in the electronics industry, advertising signs, decoration, handicrafts and other fields. .

PS (polystyrene) sheet is divided into: (PS) extruded sheet and PS polystyrene decorative board
1 Polystyrene (PS) extruded sheet: This product is made of polystyrene as the main raw material. It can be freely colored, odorless, tasteless, non-toxic, non-bacterial, and has rigidity, insulation and printing. Other advantages, mainly used in packaging, container equipment, daily decoration, general electrical appliances and construction industries.
The 2PS polystyrene decorative board is a high-molecular organic sheet extruded by a polystyrene granular molding compound on an extrusion unit. Features: PS polystyrene decorative board is a thermoplastic. The specific gravity is 1.05, the melting temperature is 150-180 ° C, the absorption rate is low, and the light transmittance can reach 88-92%. It is resistant to organic acids, alkalis, salts and lower alcohols, and soluble in esters and ketones.
3. PET hard sheet has good toughness and is a new type of material developed in recent years. With its excellent toughness, high strength, high transparency, and recyclable recycling, it is easy to burn. It does not produce harmful gases when burned. It is an environmentally friendly material and gradually bans PVC, but the price is high. It is suitable for high-grade plastic products. The plastic blister in Europe and the United States generally requires PET materials, but its high thermal melting point brings great difficulties to high-frequency packaging. In order to solve this problem, people are compounded on PET surface. The layer of PVC film, named PETG, but the price is higher. Mainly used in electronics, food, toys, color box window, collar, footwear packaging. The advantages are as follows:
1 has excellent transparency and smoothness, and the display effect is good.
2 Excellent surface decoration performance, can be printed without surface treatment, easy to press pattern, easy metal treatment (vacuum metallized layer)
3 has good mechanical strength.
4 has good barrier properties against oxygen and water vapor.
5 good chemical resistance, can withstand the erosion of a variety of chemicals.
6 Non-toxic, hygienic performance, can be packaged in food, medicine and medical equipment, and can be sterilized by Y-rays.
7 It has good adaptability to environmental protection and can be recycled economically and conveniently; when it is burned, it does not produce harmful substances. PET sheets are considered to be an ideal packaging blister material that meets (ROSH) environmental protection requirements.
