Description
Technical Field
[0001] The utility model relates to the technical field of plastic packaging box production, in particular to a blister mold for producing plastic packaging boxes. Background Art
[0002] Plastic boxes are transparent folding boxes, cylinders, lid boxes, handbags, hanging cards and other related plastic products made of PVC / PET / PP / PS, etc., which can achieve UV offset printing, silk screen printing, hot stamping / silver, frosting and other printing effects. Plastic boxes have the characteristics of increasing user experience, permanent and durable packaging, moisture-proof, waterproof, high toughness, strong transportation safety performance, and improving product grade. The main principle of the blister mold for the production of plastic packaging boxes is to heat and soften the flat plastic hard sheet, use vacuum adsorption on the mold surface, and finally cool it into shape.
