HDPE Bottle And HDPE Raw Material Characteristics

August 12, 2022

HDPE bottles refer to medicinal plastic bottles produced by blow molding and injection molding with HDPE (high density polyethylene) as the main raw material. Its characteristics are non-toxic and odorless; hardness, tensile strength and creep are better than low-density polyethylene; wear resistance, electrical insulation, toughness and cold resistance are good; chemical stability is good, at room temperature, insoluble It is resistant to corrosion by any organic solvent, acid, alkali and various salts; the permeability of the film to water vapor and air is small.

HDPE English full name High Density Polyethylene, high density polyethylene is an opaque white waxy material, the specific gravity is lighter than water, the specific gravity is 0.941~0.960, soft and tough, but slightly harder than LDPE, but also slightly stretchable. Acid and alkali resistance, organic solvent resistance, excellent electrical insulation, and can still maintain a certain toughness at low temperature. Surface hardness, tensile strength, rigidity and other mechanical strengths are higher than LDPE, close to PP, tougher than PP, but the surface finish is not as good as PP.

The general melting point of HDPE is 142 °C, and the decomposition temperature is 300 °C; the adjustable range of injection temperature is large. When injection molding, the general use temperature is 180℃--230℃; because it is an olefin plastic, it does not absorb water, and it does not need to be dried during production, but for product quality, it can be dried at 60℃ for 1hr to discharge floating water; Ethylene has high melt viscosity and small flow-length ratio, and thin-walled products may lack glue. Therefore, gates and runners are relatively large; products are prone to static electricity, and the surface is easy to absorb angstroms. The shrinkage rate is 16‰; the overflow value is 0.05mm.

ODM round HDPE bottles are mostly used for the packaging of oral solid preparations, capsules, tablets and other pharmaceuticals. As a pharmaceutical packaging, HDPE bottles are the most important. According to the different markets faced by HDPE bottles, two different testing methods can be selected: YBB standard and USP standard. The relative production process control and raw material control will be different.

About MGG Group

Shenzhen Jinlongxin Plastic Co., Ltd established in 2006, it developed into a group(Meiguo International Group Co., Ltd)(Hereinafter referred to as MGG), which has jurisdiction over Jinlongxin Plastic(H.K.) Co., Ltd, Dongguan Meiguo Plastic Co., Ltd, and Huizhou Jinlongxin Plastic Packing Co.Ltd. MGG is specialized in manufacturing and exporting different kinds of plastic packing container which are mainly used for pharmaceutical ,cosmetics and personal care products industrial, our company have 15 years OEM experience and passed ISO9001:2015 quality management certification and GMP auditing, all products are food and medical grade and all processes are produced in a modern, fully enclosed, 100000 grade dust-free workshop.This is especially important when the epidemic is still severe, and the machines are fully automatic robots, high precision, fast speed, large capacity and we have good market in United states, European, Canada,Mexico, Asia, etc . Crystal appointed MGG, a personal care plastic bottle supply company, to be their roll on deodorant bottles supplier. Most anti-perspirant deodorant was a roll-on form plastic bottle made of four components -cap, ball, bottle and the ball base. MGG team re-designed and made it a three components roll on plastic bottle. And passed the vacuum test without leakage , so easy to travel to carry .Crystal was pleased with our work and the orders has been going on for five years.The reducing of component amount means cost-saving, labor reduction and product improving, which is what every company wants. Crystal's bottles have 8 different surfaces. It is a challenge to cover a single sticker on the 8 surfaces of the bottles. This is one of the few manufacturers that can do it,Our company is one of them. MGG provides labelling services for strange shaped bottles. Colgate hello and Crystal have also commissioned MGG to develop and produce their deodorant stick container. Our fully enclosed injection molding workshop uses fully automatic machines with a daily capacity of 200,000 units.
