Basic Introduction A plastic processing technology, the main principle is to heat and soften flat plastic sheets, then vacuum adsorb them onto the surface of a mold, and cool them to form. It is widely used in industries such as plastic packaging, lighting, advertising, and decoration. Main Advantages The main advantages of vacuum packaging are that it saves raw and auxiliary materials, is lightweight, easy to transport, has good sealing performance, and meets the requirements for environmentally friendly green packaging; it can package any irregularly shaped products without the need for additional cushioning materials; the packaged products are transparent and visible, aesthetically pleasing, convenient for sales, and suitable for mechanized and automated packaging, facilitating modern management, saving labor, and improving efficiency. Vacuum-formed products are processed from plastic. The principle of product generation is to heat and soften flat plastic sheets, then vacuum adsorb them onto the surface of a mold, and cool to form. Vacuum-formed products are widely used primarily in the electronics, electrical appliances, food, hardware tools, cosmetics, toys, daily necessities, pharmaceuticals, health products, automotive, stationery, and sports supplies industries. Vacuum Packaging A general term for plastic products produced using the vacuum forming process, which are then packaged using corresponding equipment. Vacuum packaging products mainly include: blister packs, trays, and vacuum boxes. Synonyms include: vacuum covers, blisters, etc. Vacuum packaging equipment mainly includes: vacuum forming machines, punching machines, sealing machines, high-frequency machines, and edge folding machines. The packaged products can be classified into: card insert, card suction, double blister, half blister, folded blister, and triple blister. Blister Using the vacuum forming process, transparent plastic sheets are made into specific raised shapes of transparent plastic, covering the product surface to protect and beautify the product. Also known as blisters, vacuum covers, or plastic masks. According to different forms of blisters, they can be divided into: single blister, double blister, card insert blister, and card suction blister. Vacuum Box A type of vacuum-formed product with a cover and bottom; the bottom and cover connected together are called folded vacuum boxes, while those separated are called upper and lower vacuum boxes. Vacuum Tray Also known as plastic inner trays, these are made by the vacuum forming process to create plastic with specific grooves, where products are placed in the grooves to protect and beautify them. Flocked Inner Tray A type of vacuum tray made from special materials, where a layer of flocking material is glued to the surface of ordinary plastic sheets, giving the tray a soft texture to enhance the quality of the packaged products. Anti-Static Tray A vacuum tray made from special materials, with a surface resistance value less than 10 to the power of 11 ohms. It is mainly used for vacuum trays for electronic and IT products. Vacuum 'Mold' The mold used during the vacuum forming production process; the least expensive is a gypsum mold, followed by electroplated copper molds, with aluminum molds being the most expensive. The mold has small holes used for vacuum adsorbing the heated hard sheets to form vacuum products.
