The main material of Gensyu's big gallon bottle is high-density polyethylene (HDPE). Take the black Hdpe plastic nutrient empty protein food powder container as an example. This big gallon bottle has many functions, such as available multiple color options, A wide range of sizes, logos can be customized, FDA food-grade plastic materials and all covers are equipped with ventilation induction bushings to maintain internal and external air pressure balance, big gallon bottle also has many applications, such as medicines, sports nutrition products, protein powder And food or organic products, let’s take a look at what characteristics and advantages of the main material of big gallon bottle?
Here is the content list:
What is the main material of the big gallon bottle? What are the characteristics?
What is the material use of big gallon bottle?
How to pack, store and transport big gallon bottle materials?
Regarding the recycling of big gallon bottle materials.
High-density polyethylene (HDPE) is a white powder or granular product, non-toxic, tasteless, hardness, tensile strength and creep better than low-density polyethylene, big gallon bottle is the main material of big gallon bottle, resistant Good abrasiveness, electrical insulation, toughness and cold resistance; good chemical stability, insoluble in any organic solvents at room temperature, and resistant to corrosion by acids, alkalis and various salts;
[Basic characteristics] big gallon bottle medium-high-density polyethylene is an opaque white wax-like material. Its specific gravity is lighter than water, with a specific gravity of 0.941~0.960. It is soft and tough, but slightly harder than LDPE, and slightly stretchable, non-toxic.
[Combustion characteristics] The big gallon bottle is flammable and can continue to burn after leaving the fire. The upper end of the flame is yellow and the lower end is blue. It will melt when burning, dripping liquid, no black smoke, and at the same time, it emits paraffin when burning. The smell.
[Main advantages] Acid and alkali resistance, organic solvent resistance, excellent electrical insulation, and still maintain a certain degree of toughness at low temperatures. Surface hardness, tensile strength, rigidity and other mechanical strength are higher than LDPE, close to PP, tougher than PP, but the surface finish is not as good as PP.
[Main Disadvantages] Poor mechanical properties, poor air permeability, easy deformation, easy aging, easy to be brittle, less brittle than PP, easy to stress cracking, low surface hardness, easy to scratch. It is difficult to print. When printing, surface discharge treatment is required, no electroplating, and the surface is dull.
[Applications] Used for extruding packaging films, ropes, woven bags, fishing nets, water pipes; injection molding low-end daily necessities and shells, non-load-bearing components, plastic boxes, turnover boxes; extrusion blow molding containers, hollow products, bottles.
[Injection process] HDPE in big gallon bottle has countless applications, including daily necessities and food thin-walled packaging; tough and durable food and paint cans; high resistance to environmental stress cracking applications, such as small engine fuel tanks and 90- gal trash can.
The high-density polyethylene big gallon bottlecan be used to form plastic products by injection, extrusion, blow molding and rotational molding. Various types of containers, industrial accessories, medical supplies, toys, shells, bottle stoppers and protective covers can be molded by injection molding. Blow molding can be used to form various big gallon bottle, ultra-thin films, etc. Extrusion can be used to form pipes, stretch strips, straps, monofilaments, wire and cable sheaths, etc.
The big gallon bottle should be stored away from fire and insulated. The warehouse should be kept dry and tidy. It is strictly forbidden to mix in any impurities, sun and rain. Transport should be stored in clean, dry, covered carriages or cabins, and no sharp objects such as iron nails. Big gallon bottle is strictly prohibited to be mixed with flammable aromatic hydrocarbons, halogenated hydrocarbons and other organic solvents. For example, the four-liter barrel of mineral water from Nongfu Spring is this material.
HDPE is the fastest growing part of the plastic material warehouse recycling market. This is mainly due to its easy reprocessing, minimal degradation characteristics and its large number of applications in big gallon bottle packaging. The main recycling is to reprocess 25% of recycled materials, such as post-consumer recyclables (PCR), with pure HDPE to make bottles that are not in contact with food.
