What is HDPE bag?

HDPE bag stands for High Density Polyethylene - the type of particles that make up HDPE bags. HDPE bags are PE bags but in a special, more advanced form because they are made from high density PE plastic.

In addition, HDPE bags have poor flexibility, fold, and wrinkle easily, and when rubbed, they easily create loud rustling noises.

Characteristics of HDPE bags

HDPE bags have the same characteristics with LDPE bags because they are produced from Polyethylene material, the only difference is that HDPE is polymerized from Polyethylene (high density) under relatively low pressure with catalytic systems such as Catalyst, Chromium/Silic. Some basic characteristics of HDPE bags include:

• Low production costs
• Lightweight, chemical resistant
• Glossy and transparent surface
• Safe, non-toxic
• High surface smoothness
• High water resistance
• Hardness is better than other types of nylon bags
• Flexibility is average
• Easily create folds and wrinkles when folding the bag
• When rubbed, it creates a rustling noise

Types of HDPE bags distributed on the market

• Handle bag
• Shopping bag
• Garbage bag
• Roll bags used in supermarkets

Color and printing

The advantage of HDPE bags is that they come in many colors or you can choose 1 color to serve your business marketing campaign. In the medical field, HDPE bags are divided into colors, corresponding to different uses.

• Blue: Household waste bag
• Yellow: Bag for storing clinical substances
• Black: Collecting chemical and radioactive waste

Are HDPE bags safe to contain food?

According to the latest research, the safest material to make plastic bags for food preservation is high-density polyethylene (HDPE bags). The reason is that the bag is non-toxic and can withstand high temperatures (20 degrees Celsius for short periods of time, 110 degrees Celsius for long periods of time) ensuring safety when storing food and medical equipment.

Therefore, consumers can completely feel secure using HDPE bags for food. However, be careful to avoid using HDPE plastic in the microwave, containing food above 110 degrees Celsius or hot food, except for products that have been specifically designed to contain hot food.

Application of HDPE bags

HDPE bags are widely used in many areas of life, production and daily life. You can find them everywhere such as:

• Garbage bag
• Supermarket bag
• Flea market bag
• Laundry bag
• Medical equipment bag
• T-shaped bag
• Food packaging bags
