As the world of packaging continues to evolve, PVC cylinder packaging boxes serve as a testament to human innovation and adaptability. They bridge the gap between tradition and modernity, offering a glimpse into the packaging revolution that prioritizes not only functionality but also sustainability and aesthetics. In this dynamic landscape, PVC cylinder packaging boxes stand as iconic symbols of how packaging can elevate the ordinary into the extraordinary.

Blister technology, as a processing method commonly used to manufacture a variety of plastic products, is widely used in the fields of food packaging, medical devices, daily necessities and so on. Among them, PET, as a thermoplastic, is favoured for its excellent mechanical properties, transparency and food-grade safety. In this paper, we will focus on the principles and characteristics of PET food grade sheet in the blister moulding process.

PET blister packaging is a kind of plastic processing technology, the main principle is to spread the plastic hard sheet is softened by heating, vacuum adsorption on the surface of the mould, after cooling and forming, widely used in plastic packaging, lighting, advertising, decoration and other industries.

PVC packaging refers to packaging products made of polyvinyl chloride material. PVC is a common plastic with good plasticity and weather resistance. PVC packaging products usually have the characteristics of softness, transparency, durability, waterproofing, weather resistance, heat insulation, and sound insulation. The transparency is better than polyethylene and polypropylene. The hardness of hard products is higher than low-density polyethylene but lower than polypropylene. There will be a whitening phenomenon. Widely used in a variety of packaging fields.

There are many plastic products in our lives, the most common of which may also be PET plastic. PET plastic packaging refers to the use of polyethylene terephthalate, which is the name of the plastic category, including polyethylene terephthalate, polybutylene terephthalate, polyethylene terephthalate Glycol esters. Condensed from terephthalic acid and ethylene glycol, it is heat-shrinkable polyester and saturated polyester.
