What is HDPE material?
HDPE (High Density Polyethylene) is a "No. 2" plastic material marked with a triangle.
HDPE is widely used in a variety of translucent and opaque plastic containers with a thicker hand.
Commonly used in: medicine bottles, detergent bottles, shampoo bottles, shower gel bottles, milk bottles, chewing gum bottles, etc.

1. HDPE is soft and tough, and has certain flexibility, but is slightly harder than LDPE.
2. Safe, non-toxic and tasteless.
3. Resistant to various corrosive solutions, mostly used in cleaning supplies, bath supplies, etc.
4. Excellent electrical insulation
5. It can still maintain a certain toughness at low temperature.
6.Non-hygroscopic and has good water and vapor resistance, can prevent moisture and seepage.
1. Poor mechanical properties
2. Easy to deform, easy to age and become brittle, more brittle than PP.
3. Low surface hardness, easy to scratch.
4. No electroplating during printing, and the surface is dull.
The effect of HDPE material
The matte flocking effect can be made by the sandblasting process, and the hand feels soft.
Packaging and storage of HDPE
HDPE is flammable. It should be kept away from fire and insulated when stored. The warehouse should be kept dry and tidy.
Transportation should be stored in a clean, dry covered carriage or cabin, and there should be no sharp objects such as iron nails.
It is strictly forbidden to mix with flammable aromatic hydrocarbons, halogenated hydrocarbons and other organic solvents.
For example, a four-liter bottle of mineral water is this material.
Is HDPE Eco-Friendly?
HDPE is eco-friendly because it can be recycled.
HDPE regrind recovered from old milk bottles can be used in the following applications:
Large molded containers, blow molded bottles, bottle crates, kayaks, trays, gutters, rubber modified products, used as structural materials, etc. Other uses: such as ship structures, road barricades, roadside reflectors, livestock house gutters, antifreeze bottles, recycling collection containers and various large blow molding products have been developed and commercialized. Sheets made from recycled PE show good potential for application in irrigation pipes and the inner layers of dam linings.
Most of the traditional recycling and reuse are downgraded utilization. High-quality applications of recycled plastic products, such as graded utilization and high value-added utilization, have become the hot spot and focus of the industry.
Recyclable design will serve as one of the source means and important starting points for high-quality recycling.
