LDPE Bags with Handles: A Sustainable and Convenient Choice

 LDPE bags with handles, also known as plastic bags with handles, have become an indispensable part of our daily lives. They are not only simple care tools but also symbols of convenience in many activities from shopping at convenience stores to safely storing products at home. LDPE bags, short for Low Density Polyethylene, are popular for their superior features such as good bearing capacity, high durability and flexibility in use. In particular, the ability to regenerate and reuse this type of bag also contributes to efforts to protect the environment, reducing the amount of plastic waste.

Today, the use of LDPE bags is not limited to personal purposes but is still widely used by large and small businesses as an effective and economical product packaging solution. From supermarkets, fashion stores to clean food stores, LDPE bags with handles have become the top choice thanks to the outstanding features and high aesthetic value we bring.

In the next section, the article will delve into the configuration and special outstanding features of LDPE, along with the production process and common applications of this plastic bag with handle, helping readers understand better. About why we have become an indispensable product in modern life.

Structure and properties of LDPE (Low-Density Polyethylene)

Concept of LDPE

• Definition: LDPE, short for Low-Density Polyethylene, is a plastic belonging to the polyethylene group, with soft, flexible and highly elastic properties.
• Production process: LDPE is produced from ethylene polymerization under high pressure, creating a flexible and resistant plastic structure.

Strength and elasticity properties of LDPE

• Strength and elasticity: LDPE has the ability to withstand pressure and physical impacts without tearing or deforming, making it an ideal choice for the production of bags with handles.
• Application: This strength is especially important in ensuring the bag can hold and transport heavy goods without incident.

Waterproof and food safe properties of LDPE

• Waterproof: LDPE is effectively waterproof, helping to protect the products inside the bag from moisture and other environmental factors.
• Food safety: LDPE plastic does not react chemically with food, ensuring safety when used in applications related to food preservation and packaging.

Flexibility and ductility of LDPE

• Flexible: LDPE is very flexible, allowing the production of products in a variety of shapes and sizes.
• Design and manufacturing: LDPE's flexibility allows it to be used in complex designs, including bags with different types of handles.

LDPE's recyclability and environmental friendliness

• Recycling: LDPE can be recycled effectively, helping to reduce plastic waste and supporting environmental protection goals.
• Environmental protection: Choosing to use LDPE not only meets current packaging needs but also contributes to reducing the burden on the environment through high reusability and recycling.

Production process of LDPE bags with handles

Starting from plastic beads

• Raw materials: The process starts from LDPE plastic beads, which are melted at high temperature to form a liquid form.
• Blown film: The liquid plastic solution is then blown through a mold to form a thin plastic film, which is the basis of the LDPE bag.

Forms vesicles

• Laminating: After forming the film, the plastic is cooled and laminated into large sheets to prepare for cutting and welding.
• Cut to size: Plastic film is cut to the required size and shape to form the bag sections, including the front, back, and bottom of the bag.

Attach straps and complete

• Creating straps: Bag straps are often made from the same type of LDPE plastic, through a pressing and cutting process to create the desired shape.
• Welding the strap to the bag: The strap is then welded to the bag body using a heat welding machine or gluing technique, ensuring it is sturdy and has good bearing capacity.

Check quality and packaging

• Quality check: Each bag and handle is thoroughly inspected to ensure there are no defects such as tears or unstable welding.
• Packaging and distribution: The finished bag is packaged and ready for distribution to stores or directly to consumers.

Benefits of using LDPE bags with handles

Easy to transport and convenient

• Good strength: Thanks to the strength and elasticity of LDPE, this bag with handle can easily carry heavy goods without worrying about breakage or damage.
• Smart design: The handle is designed to optimize grip comfort, making moving goods easier.

Environmental friendliness

• Recycle and reuse: LDPE bags can not only be recycled to create new products but can also be reused many times, reducing the amount of plastic waste.
• Reduced pollution: Using LDPE bags can help reduce the negative impact on the environment compared to using other types of disposable bags.

Common applications of LDPE bags with handles

In retail and shopping

• Supermarkets and stores: LDPE bags are widely used in retail stores and supermarkets to hold shopping goods, from food to clothing.
• Adaptable to a wide range of goods: The flexibility and durability of LDPE allows bags with handles to be used to hold a variety of products, from light items such as food wrappers to heavy items such as groceries. Appliances.

In the food industry

• Food packaging: LDPE is safe for contact with food, making it the preferred choice for packaging fresh, frozen, and prepared foods.
• Preservation: Thanks to its ability to repel moisture and gas, LDPE bags help preserve food in the best conditions, extending the shelf life of the product.

In the medical and pharmaceutical industry

• Medical product packaging: LDPE is also used to package medical products such as bandages, disposable medical devices, and medications, ensuring they are protected from contaminants. .
• Ensures hygiene: The chemically non-reactive nature of LDPE ensures that medical products are not affected by packaging, maintaining integrity and hygiene.
