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 […]

HIPS High-impact polystyrene Chemical name : High-impact polystyreneIntroduction : HIPS is the development of rubber-modified polystyrene (ie high-impact polystyrene, HIPS) since 1950, mainly to solve the impact brittleness of PS . By adding rubber to the polystyrene substrate, various grades of high-impact polystyrene with different properties can be produced. In recent years, various special grades of HIPS […]

Definition Air-regulated preservation packaging is also called MAP or CAP in foreign countries, air-regulated packaging or displacement gas packaging, gas packaging.According to the actual needs of customers, a certain proportion of O2+CO2+N2, N2+CO2 and O2+CO2 mixed gas will be filled into the packaging to prevent the quality decline of food in physical, chemical, biological and […]

 Electrostatic Discharge (ESD: Electrostatic Discharge), should be the cause of all electronic components or integrated circuit system caused by excessive Electrical Stress (EOS: Electrical Over Stress) destruction of the main culprit.Because static electricity is usually very high instantaneously (several kilovolts >), this damage is destructive and permanent, causing a direct circuit burn down.Therefore, the prevention […]

High barrier packaging, that is, packaging materials with high barrier, the application and progress of the current industrial or industrial production prospects of the barrier materials are mainly PVDC, EVOH, PEN, nitrile resin, polyamide, etc..PVDC(polyvinylidene chloride) is characterized by low transmittance, barrier resistance and chemical resistance. EVOH is short of Ethylene vinyl alcohol copolymer, which has […]
