What are differences between OPP plastic bags and PE plastic bags? Let’s answer this question with Hanpak.
Please visit our website for more information on this topic.
1/ OPP plastic bags: Oriented polypropylene
Features: most transparent, hard, tensile strength is same at every point, can not be stretched (two-way stretch), easy to tear on both sides of the seal.
2/ PP plastic bags: Polypropylene
Features: transparence and hardness are lower than OPP’s, can be stretched (two-way stretch), tough and flexible and have good resistance.
3/ PE plastic bags: Polyethylene
Features: transparence is lower and softer than PP’s.
HDPE: high density polyethylene – feel crisp, tensile strength is higher, slightly harder, more heat resistant and more opaque than LDPE.
LDPE: low density polyethylene – feel soft, tensile strength is lower, and resilience is higher than HDPE.

1. The difference between pe bag and po bag is as follows:
PE packaging bags are made of LDPE and LLDPE raw materials made by addition polymerization of low-density ethylene, which are melted and blow-molded after batching. The bag has 90% transparency, is soft, has a low melting point, has good toughness, is non-toxic, and is not easy to tear. Products are often used in industrial packaging such as clothing, electronics, toys, etc.
PO bag is made of HDPE and low-density polyethylene LLDPE made by addition polymerization of high-density ethylene, melted and blow-molded after batching. The bag has 60% transparency, is hard, has high melting point, is non-toxic, and is easy to be brittle. Products are often used in shopping bags, handbags, shopping mall bags, and industrial packaging bags.
The common point of PE and PO plastic bags are raw materials made of ethylene addition polymerization. The difference is that their density is different, and the products produced are also used for different purposes.
2. The difference between pe bag and opp bag is as follows
PE bag and opp bag are two common plastic bags in the market. Although the use of both can bring more benefits to people, there are also differences between the two. So, what is the difference between pe packaging bag and opp bag? The following is a brief introduction to this problem.
Appearance: There is a clear difference in appearance between pe bags and opp bags. Under normal circumstances, the former is translucent and has a good feel, while the latter is transparent and has good toughness, and it feels smooth to the touch. The two can be distinguished well by the appearance.
Purpose: There is also a difference between the use of pe bags and opp bags. Under normal circumstances, pe bags are used to hold ordinary products, such as electrical appliances, toys or tools, and this phenomenon occurs because such products have relatively high With good toughness, the probability of damage will be reduced, and OPP bags can be used as packaging for clothing products because of the good transparency of the bags.
Through the above introduction, people should know the difference between pe bags and opp bags. In order to better meet the needs of use, then they should choose the appropriate packaging bags according to the actual choices, so as to avoid unnecessary economic losses. I also hope that the above introduction can help people.
