Polyethylene terephthalate plastics, mainly including polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) PET has a highly symmetrical molecular structure and a certain ability to crystallize, so it has high film-forming properties and properties. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, PET has excellent abrasion resistance, […]

PET sheet is a thermoplastic environmentally friendly plastic product, which is widely used in the packaging of cosmetics, food electronics, toys, printing and other industries. PET sheet is also known as polyester rigid film, and its scrap and waste can be recycled. PET products have the characteristics of no crystal point, high transparency, good gloss, […]

PP is the abbreviation of polypropylene, which is one of the most active plastic varieties. Understanding its structure and characteristics is very necessary for rational design of formula structure and rational selection of processing. Let's take a look at the characteristics and basic properties of pp plastics. First, the characteristics of pp plastic 1. Good […]

Today, plastic sheets are used more and more widely. Plastic sheets can be seen on construction sites, factories, decoration, etc. There are many kinds of plastic sheets on the market, and different plastic sheets have different uses. What are the advantages of plastic sheets? 1. The surface is smooth and the texture is very goodIf […]

Blister packaging has a good sales display effect because the contents of the package are visible, and it is widely used in packaging production. In view of the main failures of poor product blistering in the production process of actual plastic sheets, combined with actual production experience, the influencing factors were analyzed from the aspects […]

The influence of the blister process The blister process includes: the process of printing and coating blister oil and the process of blister heat sealing. At present, there are three ways to realize the coating process: offline oiling machine full plate oiling, screen printing partial oiling, offset printing connection oiling. Offline coating and blister […]

Plastic packaging sheets are often used to produce disposable plastic cups, plates, bowls, dishes, boxes and other thermoforming products, which are widely used in the packaging of food, vegetables, fruits, beverages, dairy products, industrial parts and other fields. The plastic sheet has good flexibility and transparency, and can be easily made into popular styles of […]

1. PVA coated high barrier plastic film PVA-coated high-barrier film is made by coating PVA with nano-inorganic substances on polyethylene film, then printing and compounding. On the premise of not greatly increasing the cost, the technical bottleneck of poor barrier performance of the three-layer polyethylene co-extruded packaging film is solved. PVA coated high-barrier milk film […]

First, PP is an environmentally friendly material.Second, the difference between PP and PVC can be clearly distinguished in terms of appearance and feel;PP feels harder while PVC is relatively soft. The best way to test is to burn these two materials with an open flame. The black dusty form is PVC but PP does not. […]
