A plastic processing technology, the main principle is the flat plastic sheet heated to soften, vacuum adsorption on the surface of the mold, cooling after molding, widely used in plastic packaging, lighting, advertising, decoration and other industries.
Plastic packaging products mainly include: blister. tray. Plastic boxes. Also is known as: vacuum hood. Blister, etc., mainly plastic packaging equipment package boast: plastic molding machines. punch. Sealer. High-frequency machine. Photorefractive machine. Package formed packaging products can be divided into: plug-in. Double blister card blister. Half blister. Clamshell. Triple bubble shell.
Blister process transparent hard plastic made specific convex-shaped sheet of transparent plastic, cover the surface of the product, protect and beautify the role of products,
The ordinary hard plastic surface layer of solute material glue so that the surface of the tray kind of solute feel, to improve the quality of packaging,
Using a special process modified materials, plastic trays, the resistance of the material surface is less than 11 times to put 10 ohms. Mainly used in electronics. IT products static tray.
Plastic mold production, the lowest cost is the cast, followed by plating copper mold is the most expensive aluminum mold, mold drilled a small hole for vacuum heat of adsorption of hard films, the formation of plastic products.
We often say that the blister, blister forming machine will heat softening of hard plastic adsorbed on the surface of the mold after cooling, form the plastic irregularities.
Blister cutting: blister packaging molded plastic products, after punching the sheet with large sheet die cutter into a single product.
Flap: plastic packaging products there is a package called plug-ins, you need to use three sides blister folding machine fold to the back, so that the next Road packaging process, paper card into the folding, the formation of the card packaging.
Heat sealing: a blister packaging technology, with a sealer surface coated paper card with blister plastic oil and also together to form a blister card packaging,
High frequency sealing: a blister packaging technology to produce machines with high frequency ultrasound, will blister and blister bonded together to form a double blister packaging, and the difference is that the high-frequency sealing, ultrasonic not only could seal the PVC. PET. PETG materials, can also seal PET material and package products for an electromagnetic damage, particularly suitable for packaging of electronic products: The downside is that ultrasound Edge only point intervals, and is generally a time a closure edge .
