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. […]

Polypropylene (PP) resin has the characteristics of low density, non-toxicity, easy processing, warping resistance and good insulation. It is suitable for injection molding, extrusion blow molding, thermoforming and other processing methods. widely used.  PP plastic characteristics Non-toxic, tasteless, low density, strength, stiffness, hardness and heat resistance are better than low pressure polyethylene, can be used […]

As we all know, PVC plastic sheet and PET plastic sheet are one of the two more commonly used plastic products. Then the question is coming, you knowWhat are the differences between PVC plastic sheet and PET plastic sheet? How to correctly distinguish between PVC plastic sheet and PET plastic sheet? Now, let me brief […]

Polypropylene is a thermoplastic resin obtained by the polymerization of propylene, referred to as PP. Polypropylene has good heat resistance, and the products can be sterilized at temperatures above 100 ° C, and will not deform at 150 ° C under the condition of no external force. The chemical stability of polypropylene is very good, […]

PP sheet is made of polypropylene resin as the main raw material, adding various process color masterbatches, toughening agents and brightening agents, and is made by mixing, plasticizing extrusion, three-roll calendering, cooling, traction, and winding. PP sheet has the characteristics of non-toxic, tasteless, hygienic, high mechanical strength and good barrier properties, and can be used […]

PE plastic is odorless and five poisonous, feels like wax, can withstand low temperature, good chemical stability, low water absorption, high rigidity, hardness and strength, and strong radiation resistance. But PE plastic is very sensitive to environmental stress (chemical and mechanical action) and has poor heat resistance.   PP is one of the most widely […]
