What is the workflow of vacuum box packaging? Dongguan Shengyao manufacturer introduces to you:

1. The raw materials for vacuum packaging mainly include PVC, PS, PP, PET, PETG flocking, anti-static, conductive other materials. Blister packaging products mainly include: blister, tray, blister box, synonymous with: vacuum cover, blister, etc.

2. The blister packaging equipment mainly includes: blister packaging machine, blister molding machine, punching machine, sealing machine, high-frequency machine, folding machine. The packaging products formed by packaging can be divided into: card insertion, suction card, double vacuum forming, semi vacuum forming, double fold vacuum forming, triple fold vacuum forming, etc.

3. The working process of vacuum packaging:

(1) Mold making processing: According to the required sample specifications, first make a pipeline centrifugal pump vacuum forming mold. Under normal circumstances, gypsum is used to manufacture bubble wrap packaging molds, but wood carved metal products are also used as molds. After the mold is made, let it dry naturally. Then, based on the specific surface condition of the product, use a 1-2mm drill bit to drill many small holes in the low concave areas that do affect the appearance of the product packaging. If it is used for packaging products such as boxes, it is necessary to drill some small holes on the four sides to extract air during the blister production process. After drilling the mold, the gypsum mold must harden. The hardening method is to soak air dry in a saturated alum solution. -Dongguan vacuum formed box

(2) After the mold is completely dry, install the mold into the upper iron plate of the vacuum chamber, then load the plastic sheet into the appropriate specifications according to the mold size, then place the sheet in a heated wooden cabinet to fully fix it. Then, place the wooden cabinet plastic sheet together on a constant temperature furnace for softening treatment.

(3) Place the softened plastic sheet together with the wooden cabinet in the vacuum chamber, turn on the suction switch to clean the air in the vacuum chamber. After the plastic sheet cools down, you will obtain the same concave packaging process mold as the mold.

(4) Bubble wrap packaging organization; The products produced by trimming organizing are finished products that can be sold after packaging.
