LDPE bags are incredibly versatile and widely used in various industries. They can be used as packaging materials for food, cosmetics, and pharmaceuticals.
LDPE bags are also great for carrying liquids, such as water, juice, and even fuel. Their flexibility and moisture resistance make them an excellent choice for these applications.
One of the main advantages of LDPE bags is their lightweight and flexible nature, making them easy to transport and store. This also makes them a cost-effective option for businesses.
LDPE bags can be recycled, reducing waste and promoting sustainability.
What Are LDPE Bags?
LDPE bags are a type of plastic bag made from a type of plastic called low-density polyethylene.
They are flexible and lightweight, making them easy to carry and store.
LDPE bags can be used for a variety of purposes, including packaging and carrying food, as well as storing items like clothes and linens.
LDPE is a type of thermoplastic, which means it can be melted and reformed multiple times without undergoing any significant chemical change.
LDPE bags are also known for their water resistance, making them a popular choice for packaging items that need to stay dry.
Their low density also makes them less expensive to produce than other types of plastic bags.
LDPE bags are widely used in the packaging industry due to their durability and versatility.
Types of LDPE Bags
LDPE bags come in various types, each with its own unique characteristics.
Tie-on bags, also known as twist-tie bags, are a popular choice due to their ease of use.
These bags are made with a small loop at the top that can be tied with a twist tie, making them ideal for packaging small items.
Stand-up pouches are another type of LDPE bag, designed to stand upright on shelves.
They often feature a spout or zipper for easy dispensing of contents, making them perfect for packaging liquids or powders.
HDPE vs LDPE
HDPE is more rigid and durable than LDPE.
Its crystalline structure offers greater strength and opacity, making it a popular choice for packaging.
HDPE has a higher melting point of 275 °F, allowing it to withstand higher temperatures than LDPE.
LDPE is softer and more flexible than HDPE, but also more prone to cracking when under stress.
HDPE's better chemical resistance makes it a better option for storing chemicals and other substances that can damage LDPE.
Easy Tear
Easy Tear LDPE bags are a convenient option for many applications. They allow technicians to open the bag with gloved hands, reducing the risk of damage from knives, blades, or scissors.
The Easy Tear formulation is available in multiple thicknesses, with or without re-closable zippers. This makes it a great choice for gamma-irradiated products.
Here are some key physical properties of Easy Tear LDPE bags:
Easy Tear LDPE bags have excellent elongation properties, with a minimum of 300% in the machine direction and 400% in the transverse direction. This flexibility makes them suitable for a range of applications.
The seal strength of Easy Tear LDPE bags is also impressive, with a minimum of 30N and 12 lbs, respectively. This ensures that the bags remain secure and intact during use.
Cleanroom Zip Lock

Benefits and Advantages
LDPE bags are an economical choice for packaging, offering a lower cost compared to other materials.
Their environmental friendliness adds to their appeal in an increasingly eco-conscious market.
The perforations in LDPE bags effectively alleviate tension that often builds up during storage and transit.
This feature is vital for maintaining the bag's structural integrity, ensuring that products reach their destination in pristine condition.
LDPE bags are crafted from a material renowned for its resistance to cold temperatures, making them ideal for storing and transporting temperature-sensitive products.
These bags are widely used for various food packaging applications, such as standalone packaging for single food types, overwrap for additional protection over other packaging materials, and as part of a tray pack system.
Their versatility makes them a popular choice for brands in the food sector, catering to a range of packaging needs.
Both LDPE and LLDPE bags have exceptional moisture retention properties that keep moisture within the package while preventing the water from getting into contact with the product inside the package.
LDPE bags are also recyclable, making them a more sustainable option for packaging.

By choosing recyclable LDPE bags, you're supporting a more circular economy and helping to minimize the environmental impact of packaging.
Recycling Differences
LDPE and HDPE plastic bags can't be recycled together, despite being made from the same materials. This is because they have different recycling numbers: LDPE is recycling number 4, while HDPE is recycling number 2.
LDPE bags are more difficult to recycle due to their soft structure, which can get caught in recycling machinery.
While they have their differences, LDPE and HDPE share some common features, including being lightweight materials with a tensile strength of 0.20 to 0.40 N/mm.
HDPE is also easier to recycle than LDPE, thanks to its more rigid structure that can run through recycling equipment more smoothly.
Here are some key similarities between LDPE and HDPE:
- Lightweight materials
- Tensile strength from 0.20 to 0.40 N/mm
- High-impact strength
- Chemical resistance
- Resistance to water vapor and weathering
- Recyclability
- Low manufacturing cost
