1. What is PET material？ PET is a polymer material, the full name is polyethylene terephthalate, which is synthesized by transesterification of dimethyl terephthalate and ethylene glycol or esterification of terephthalic acid and ethylene glycol, and then the condensation reaction. This material is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface....
Customized process 1. Design and sample making The packaging process starts by designing the packaging format. We provide 3D drawings according to your requirement. After your confirming,we will make the sample mold. The sample mold are divided into two types: plaster mold and wooden mold. It takes 5-7 working days to finish sample making. After the sample mold is finished, we can make s...
1. What is the product made of : PLA, also known as polylactic acid, is a polyester made through the fermentation under controlled conditions of a carbohydrate source like corn starch, tapioca roots, or sugarcane. Plants → sugar →fermentation（lactic acid）→monomer production (lactide)→polymer production→PLA→polumer conversion→sheet of PLA for packaging or PLA for fibers etc. 2.&nb...
1. Introduction of the material: PVC is polymerized from vinyl chloride monomer and is one of the commonly used thermoplastics. Its trade name is referred to as "Chloroplastic". Pure polyvinyl chloride resin is a hard thermoplastic material, its decomposition temperature is very close to the plasticization temperature, and its mechanical strength is poor. Therefore, it is impossib...
1. What is PP material? pp stands for polypropylene material in plastics. Polypropylene is a thermoplastic resin obtained by polymerizing propylene. The copolymer-type PP material has lower heat distortion temperature (100°C), low transparency, low gloss, and low rigidity, but has stronger impact strength. The impact strength of PP increases with the increase of ethylene content. ...
1. What is the product made of : PS (polystyrene plastic) refers to a class of plastics including styrene groups in the macromolecular chain, including styrene and its copolymers. Its characteristics are colorless, odorless and tasteless. PS is a relatively old plastic. After many years, its production process is relatively perfect. PS has good transparency (light transmittance of 88%-92...
1. Introduction of CPET: CPET is a polyethylene terephthalate material, which is odorless, tasteless, colorless and non-toxic. It is recognized as the best food packaging material in the world today. Products made of CPET material can be processed directly in the oven for various foods. It will not release any harmful substances and gases during the heating process, which is called gree...
1. What is mold rapping? When the customer confirms the sample, we will use the plaster mold for proofing as the master mold. After the master mold is electroplated with copper, the mold for production is made according to a certain number and position. 2. Type of Mold Conventional molds are divided into three types: plaster molds, copper molds, and aluminum molds. Among them, the plaster mold is ...
