The main material of the PETG bottle is PETG, PCTG is a non-crystalline copolyester. In its production process, since a certain amount of ethylene glycol is replaced by 1,4-cyclohexane dimethanol (CHDM), crystallization can be prevented, thereby improving manufacturing and transparency. So, do you know the advantages of PETG bottles? Here are some answers.

PETG is one of the few environmentally friendly plastic materials so far.

PETG bottle is a thick transparent product with good light transmittance.

PETG bottle has high toughness, excellent tensile performance, and good impact resistance.

Due to the high light transmittance of the PETG jar​, the surface quality of PETG products must be strict, without any markings, pores, and whitening, haze, black spots, discoloration, poor gloss, and other defects, so PETG scraps and equipment are used throughout the injection molding process. The design of PETG jar molds and even products must pay great attention to and put forward strict and even special requirements. Secondly, because most PETG jars have high melting points and poor fluidity, to ensure the surface quality of the products, manufacturers of PETG scraps often need to make fine adjustments to process parameters such as temperature, injection pressure, and injection speed, so that the PETG can be filled with the mold. It will not produce internal stress and cause product deformation and cracking. So what are the points of attention in PETG jar injection molding? Let's take a look together next.

Although injection molding machines have in turn adopted value cuts and varied advantageous promotions, the event trend of Plastic caps created by compression molding technology has not diminished. Since 2001, the amount of compression molding instrumentation purchased by Chinese customers has greatly exceeded that of injection molding instrumentation. Next, let's take a look at the introduction of Plastic caps. Here are some answers.

What are the advantages of a PET Plastic cap?

Plastic caps can play a protective role.

According to the use of Plastic caps, it can be divided into breathable Plastic caps and air impermeable Plastic caps. Do you know other classifications of Plastic caps? Do you know what its craftsmanship is? What is the difference between the processes? Next, let's take a look at the classification of Plastic caps. Here are some answers.

According to the form of Plastic cap, it can be divided into a single-piece cap and a double-piece cap.

According to the production process, Plastic caps can be divided into injection molding caps and compression molding caps.
