Brief introduction of commonly used workpieces and processes for blister packaging

Blister:

A plastic processing technology, the main principle is to heat the flat hard plastic sheet to soften it, then use vacuum to absorb it on the surface of the mold, and then shape it after cooling. It is widely used in plastic packaging, lighting, advertising, decoration and other industries.

Blister packaging:

The general term for plastic products produced by blister technology and packaged with corresponding equipment. Blister packaging products mainly include: blister, tray, blister box, synonyms are: vacuum cover, blister, etc. Blister packaging equipment mainly includes: Blister forming machine, punching machine, sealing machine, high frequency machine, folding machine. The packaging products formed by encapsulation can be divided into: insert card, suction card, double blister, half blister, half-fold blister, three-fold blister, etc.

vacuum cover

The transparent plastic hard sheet is made into a specific shape of transparent plastic by using the blister process, and it is covered on the surface of the product to protect and beautify the product. Also known as blister, vacuum cover

tray:

Also called plastic inner support, the plastic hard sheet is made into a plastic with a specific groove by using the blister process, and the product is placed in the groove to protect and beautify the product.

Flocking inner support:

It is a blister tray made of special materials. A layer of velvet material is glued on the surface of ordinary plastic hard sheets, so that the surface of the tray has a velvet feel, which is used to improve the grade of packaging products.

Antistatic Tray:

It is a blister tray made of special materials, and the resistance value of the surface of the material is less than 1011 power ohms. Mainly used for blister trays of electronics and IT products.

Blister mold:

For molds used in blister production, plaster molds are the cheapest, followed by electroplated copper molds, and aluminum molds are the most expensive. The mold is drilled with small holes, which are used to vacuum heat the hard sheet to form a blister product.

Blister forming:

It is the blister we often talk about. A blister molding machine is used to absorb the heated and softened plastic hard sheet on the surface of the mold, and after cooling, it forms a concave-shaped plastic.

Blister cutting:

The plastic products after blister molding are cut into individual products by punching a large sheet with a knife die.

Hem:

There is a kind of blister packaging called card packaging. It is necessary to fold the three sides of the blister to the back with a folding machine so that in the next packaging process, the paper card is inserted into the folding edge to form a card packaging.

Heat seal:

It is a blister packaging process. The paper card coated with blister oil and the blister are heat-bonded together by a sealing machine to form a blister pack.

High frequency sealing:

It is a blister packaging process, using a high-frequency machine to generate high frequency, and bonding the blisters together to form a double-blister package.

Ultrasonic sealing:

It is a blister packaging process, which uses an ultrasonic machine to generate ultrasonic waves, and glues the blisters together to form a double-blister package. The difference from high-frequency sealing is that ultrasonic waves can not only seal PVC and PETG materials, but also PET material can be sealed, and there is no electromagnetic damage to the packaged products, especially suitable for the packaging of electronic products; the disadvantage is that ultrasonic edge sealing can only be dotted at intervals, and generally only one straight edge is sealed at a time.

Shenzhen Jiazhao High Tech Co., Ltd. has been specializing in the production for many years: blister packaging sealing machine, three-sided automatic folding machine, blister heat sealing machine, double blister blister packaging high frequency melting cutting machine, ultrasonic blister sealing machine, suction Plastic sealing bakelite molds, high-frequency sealing molds, ultrasonic welding molds, etc., are sold all over the world and won the trust of customers.
