Blister process details

Blister: a plastic processing technology, the main principle is to flatten the plastic hard sheet heating soft, vacuum adsorption on the mold surface, after cooling molding, widely used in plastic packaging, lighting, advertising, decoration and other industries.

Blister packaging: The use of plastic technology to produce plastic products, and use the corresponding equipment to the product of the general term. Blister packaging products include: blister, tray, plastic boxes, synonym: vacuum cover, blisters and so on. Blister packaging equipment mainly includes: plastic molding machine, punch, sealing machine, high frequency machine, folding machine. Packaged packaging products can be divided into: card, card, double-bubble shell, half-bubble shell, folded shell, three-fold bubble shell and so on.

Foam shell: The transparent plastic hard sheet is made into transparent plastic with a certain convex shape by a blister process and covers the surface of the product to protect and beautify the product. Also known as blisters, vacuum covers

Tray: Also known as plastic inner tray, the plastic hard sheet is made into a special grooved plastic by a plastic blister process, and the product is placed in the groove to protect and beautify the product.

Flocking and inner tray: It is a kind of plastic tray using special materials. It will stick a layer of velvety material on the surface of ordinary plastic hard sheets, so that the surface of the tray has a kind of velvet texture, which can be used to improve the grade of packaging products.

Antistatic tray: It is a plastic tray with special materials. The surface resistance of the material is less than 10 11 ohms. It is mainly used for plastic trays for electronics and IT products.

Plastic molds: molds for plastic production, the lowest cost is a plaster mold, followed by a copper plating mold, and the most expensive is an aluminum mold. The mold is drilled with small holes for the vacuum adsorption of the heated hard sheet to form a plastic product.

Blister molding: It is the plastic blister that we often talk about. It adopts plastic blister molding machine to absorb the plastic soft film heated and softened on the surface of the mold. After cooling, it forms plastic with concave and convex shapes.

Plastic cutting: Plastic products after plastic molding pass through a punch press to cut a large sheet of material into a single product.

Folding: There is a kind of card packaging in blister packaging products, and the three sides of the blister shell need to be folded back to the back with the hem folding machine so that the paper card is inserted into the fold in the next packaging process to form the card packaging. .

Heat sealing: It is a plastic packaging technology. The paper card coated with plastic oil on the surface and the bulb are heat sealed together to form a blister card package.

High-frequency sealing: It is a blister packaging process. It uses a high frequency machine to generate high frequency, and bonds the bubble shell and bubble bulb together to form a double blister package.

Ultrasonic sealing: It is a blister packaging process. Ultrasonic machine is used to generate ultrasonic waves. The blister and the blister are bonded together to form a double blister package. Unlike high frequency sealing, ultrasonic waves not only seal PVC and PETG. Material, PET material can also be sealed, and there is no electromagnetic damage to the packaged product, especially suitable for electronic product packaging; The disadvantage is that the ultrasonic edge sealing can only be a dot-like shape, and generally only one straight edge is enclosed at a time.
