LDPE plastic bags are one of the most common plastic bags used in Malaysia.
Although many plastic bag suppliers in Malaysia use a variety of plastic bag materials such as:
LDPE is still one of the most sought after. This article covers the characteristics of LDPE plastic bags and their application.
Low-density polyethylene (LDPE) resins are often used to produce plastic bags. LDPE plastic bag suppliers in Malaysia mainly use the material for the creation of utility bags and food packaging.
LDPE has excessive branching with very low density. The low density means the LDPE polymer has the minimum compact molecular structure. Thus, LDPE plastic bags are more flexible than other bags. However, they have very low tensile strength.
The LDPE plastic bags are extremely lightweight. Moreover, they have a low melting point, which makes them suitable for heat sealing various products. LDPE plastic bag suppliers in Malaysia can completely rely on the resistance and resilience of this material. They have excellent resistance to acids, alcohols, esters, and bases. Similarly, LDPE is resistant to ketones and oils.
The density of the LDPE is between 0.917 and 0.930 g/cm. Plastic bag suppliers in Malaysia can use the LDPE plastic bags in almost any industry and application because they are not reactive at room temperatures.
The use of very strong oxidizing agents can disturb the molecular structure of the LDPE. Furthermore, it can withstand 80 °C for an extended period and 90 °C for a short time. In short, its flexibility and toughness have made LDPE plastic bags a popular choice.
LDPE plastic bags are commonly compared with HDPE plastic bags; however, they are very different. LDPE plastic bags are thicker and more stretchable than HDPE plastic bags. Moreover, LDPE plastic bags have more shine than HDPE plastic bags.
Compared to other types of plastic material like HDPE, LDPE has much more branching that weakens the polymer’s intermolecular forces. Hence, it has lower tensile strength and higher resilience. The primary logic behind LDPE’s low density is that its molecules are closely packed with each other and are less crystalline due to excessive branching.
LDPE is primarily used to produce plastic bags, containers, dispensable bottles, and plastic components of computers and smart devices. Many other products are manufactured from LDPE, such as stretch films, bubble wraps, and garment bags. However, plastic bags are the most prevalent use of LDPE.
Restaurants, hotels, and the food industry commonly use LDPE plastic bags for food packaging. The excellent strength and low-density of LDPE make it suitable to create LDPE refuse bags. Laundries and butcheries mainly use the services of LDPE plastic bag suppliers in Malaysia to get the perfect LDPE bagging solution because it is cheaper than other types of bag.
LDPE plastic bags are beneficial because they are soft and flexible with optimum impact resistance, especially at low temperatures. It is easy to process the LDPE bags in molten form. As a result, LDPE is often used to manufacture stretch wraps, shopping bags, and traditional plastic bags. The LDPE plastic bags’ resistance to numerous chemicals and solvents makes them suitable for use by different industries.
They are even capable of withstanding sterilization chemicals like gamma radiation and formaldehyde, which is usually very destructive to other types of plastic bags. Moisture resistance properties of LDPE plastic bags allow people to keep the content safe and fresh for a long time.
Undoubtedly, LDPE plastic bags are a highly beneficial and feasible bagging solution. The availability of the raw material facilitates quick and easy manufacturing of the LDPE.
As a result, the LDPE plastic bags are very cost-effective as well. Both general consumers and plastic bag suppliers in Malaysia can benefit from these bags because they are reliable and cheaper than many other types of plastic bags.
