Raw materials for producing PE Drawstring Bags

Polyethylene (PE) is the main material used in the production of PE Drawstring Bags thanks to its outstanding properties.

Introduction to Polyethylene (PE)

Polyethylene (PE) is a thermoplastic synthesized from ethylene, an organic compound. This type of plastic is widely used in many industries, especially in bag production thanks to its high durability and flexibility. PE has many applications thanks to its heat resistance, chemical resistance and good mechanical strength.

Characteristics of Polyethylene

• High durability: Polyethylene has good mechanical durability, helping the bag not be easily torn or damaged during use.
• Waterproof ability: PE has excellent waterproof ability, helping to protect items inside from moisture and dirt.
• Chemical resistance: PE is resistant to a wide range of chemicals, making it suitable for a variety of usage environments.
• Flexibility: PE can be processed into many different shapes and sizes, suitable for many uses.

Polyethylene types are often used in the production of drawstring bags

• Low-Density Polyethylene (LDPE): LDPE has high flexibility and is easy to process, suitable for thin and light bags. LDPE is often used for products that require flexibility and good tensile strength.
• High-Density Polyethylene (HDPE): HDPE has higher durability and better tear resistance, suitable for bags containing heavy objects. HDPE has better hardness and bearing capacity than LDPE, suitable for applications requiring high durability.

Advantages of using Polyethylene in the production of drawstring bags

• Durability and longevity: Bags made from PE have a long lifespan and can withstand physical and chemical impacts.
• Recyclability: Polyethylene is easily recycled, helping to minimize negative impacts on the environment. Using PE bags helps reduce the amount of plastic waste, contributing to environmental protection.
• Versatility: PE bags can be used for many different purposes such as storing gifts, personal items, or packaging for industrial products. This makes PE bags a flexible and convenient solution for many needs.

Production process of PE Drawstring Bags

The production process of PE Drawstring Bags includes many steps from preparing raw materials, creating PE film, cutting and processing bags, attaching drawstrings, to quality checking and packaging.

1. Prepare materials

Checking and preserving PE plastic beads:

• PE plastic pellets are supplied in granular form and need to be stored in cool, dry conditions.
• Before being put into production, PE plastic beads are thoroughly tested to ensure there are no impurities.

Ensuring raw material quality:

• PE plastic pellets must meet quality standards to ensure the final product has the best quality.
• Carefully prepared raw materials are the first and important step in the production process.

2. Create PE film

Putting PE plastic pellets into the extruder:

• PE plastic pellets are fed into the extruder, where they will be melted at high temperature.

Creating PE film from plastic beads:

• The extruder forces the melted plastic through a narrow gap to form a thin film.
• This process is strictly controlled to ensure the thickness and uniformity of the PE film.

PE film cooling:

• After being created, the PE film will be cooled with air or water.
• Then, the PE film is rolled into large rolls for storage.

PE film quality control:

• The film forming process requires high precision to ensure there are no holes or cracks.
• PE film must meet quality standards before moving on to the next processing steps.

3. Cut and process bags

Cut PE film into sheets:

• The PE film roll is put into the cutting machine to cut into sheets of appropriate size.

Heat sealing to form bags:

• PE film sheets are put into a heat sealing machine to form bags.
• The heat welding machine uses high temperatures to melt the PE film at the positions that need to be welded, then cools so that these positions stick together tightly.

Carefully check the PE bag:

• After being heat-sealed, the bag will be thoroughly inspected to ensure there are no technical errors such as uneven welding or tears.

Prepare standard bags for the next step:

• Bags that meet the standards will be moved to the next step.
• This stage requires high precision and technique to ensure the bag has the best durability and quality.

4. Attach drawstring

Choose the appropriate drawstring type:

• Drawstrings are usually made from nylon or polyester fibers, which are highly durable and easy to use.

Attach the drawstring to the bag mouth:

• The drawstring is threaded through the top of the bag and secured with buckles or knots to ensure security.

Check the operation of the drawstring:

• The process of attaching the drawstring requires meticulousness and dexterity to ensure the drawstring operates smoothly and does not slip.
• After attaching the drawstring, the bag will be inspected one last time to ensure quality before packaging.

Complete the bag with drawstring:

• Perfection in every small detail helps the final product meet the highest standards of quality and durability.

5. Check quality and packaging

Final quality check:

• After completing the production steps, the drawstring bags will be quality checked again.

Packaging and storage:

• Standard bags will be carefully packaged and stored in the warehouse.

Prepare for shipping and distribution:

• Drawstring bags are ready for shipping and distribution to customers.
• Careful inspection and packaging ensures that products reach consumers in the best condition.

Advantages and applications of PE Drawstring Bags

PE Drawstring Bags have many outstanding advantages and are widely used in many different fields.

Advantages of PE Drawstring Bags

• Durable:PE drawstring bags have high mechanical strength, helping them withstand strong pulling forces and not tear easily. This makes them ideal for holding items that are heavy or have sharp edges.
• Waterproof ability:With excellent waterproof ability, PE bags protect the contents inside from moisture and dust. This is especially useful when used in humid or outdoor environments.
• Flexibility and ease of use:PE drawstring bags are easy to open and close thanks to the drawstring design, making it more convenient for users to use. This design also saves time when packing and removing items from the bag.
• Recyclability and environmental friendliness:Polyethylene is a recyclable plastic, helping to minimize negative impacts on the environment. Using recycled PE bags helps reduce the amount of plastic waste, contributing to protecting a clean, green environment.

Application of PE Drawstring Bags

• Use in sports and tourism: PE drawstring bags are very popular in sports and travel activities. They are used to store clothes, shoes, and personal items when going to the gym, swimming, or picnicking. Their convenience and durability make users feel secure when carrying them during outdoor activities.

• Packaging and advertising: Many companies use PE drawstring bags as packaging for products or for brand advertising. Bags can be printed with logos, slogans, and advertising messages, helping to increase brand recognition and reach customers effectively.

• Gifts and events: PE drawstring bags are a great choice for storing gifts at events, conferences, and parties. They not only protect the gift but also make a good impression on the recipient thanks to its beautiful and convenient design.
• Household use: PE drawstring bags are also widely used in homes to store daily items such as children’s toys, laundry, and personal items. They help keep living spaces neat and tidy.
