Industry knowledge

How are poly bags made? 

Material Selection: Poly bags are commonly made from low-density polyethylene (LDPE) or high-density polyethylene (HDPE). These materials are chosen for their flexibility, durability, and affordability.
Resin Preparation: The selected polyethylene resin is melted down and mixed with various additives, such as colorants, stabilizers, and processing aids. These additives help enhance the properties of the final poly bag, such as its strength, clarity, and UV resistance.
Extrusion: The resin mixture is then fed into an extruder, which consists of a large heated screw encased in a barrel. The screw rotates, pushing the molten resin forward while melting it completely. The heat and pressure generated during this process ensure uniformity and consistency in the molten plastic.
Film Formation: The molten plastic exits the extruder through a die, which is a specially designed opening that shapes the plastic into a thin, continuous tube. The dimensions of the die determine the width and thickness of the poly bag.
Cooling and Shaping: As the plastic tube emerges from the die, it enters a cooling chamber where cool air or water is blown onto the tube. This rapid cooling solidifies the molten plastic, transforming it into a solid film.
Cutting and Sealing: The solid film tube is then passed through a series of rollers and blades that cut it into individual bags of the desired length. At the same time, heat is applied to seal the sides of the bags. The type of seal can vary, including options like flat seals, side seals, or bottom seals.
Finishing Touches: Additional processes may be employed to add features to the poly bags, such as adding handles, perforations, or printing custom designs, logos, or information.
Quality Control: Throughout the manufacturing process, quality control measures are taken to ensure the poly bags meet the required standards. This includes checking for defects, such as holes or weak seals, as well as verifying dimensions, thickness, and overall appearance.

What are the different types of poly bags?

Poly bags, also known as polyethylene bags or plastic bags, are versatile packaging materials used for various purposes. Here are some of the different types of poly bags commonly available:
Clear Poly Bags: These bags are transparent and allow visibility of the contents. They are commonly used for storing and displaying items such as apparel, jewelry, food, and other small products.
Reclosable Poly Bags: Also known as ziplock bags or resealable bags, these bags have a built-in zipper or slider closure mechanism that allows repeated opening and closing. They are ideal for storing items that need to be accessed frequently or kept airtight, such as snacks, hardware, and small parts.
Poly Mailers: Poly mailers are lightweight, durable bags used for shipping and mailing purposes. They are often made from a combination of polyethylene and other materials to provide protection against tearing, punctures, and water damage. Poly mailers may come with a self-sealing adhesive strip for easy closure.
Bubble Mailers: These bags have a layer of bubble wrap material on the inside to provide cushioning and protection during shipping. They are commonly used for mailing delicate or fragile items like electronics, cosmetics, and small gifts.
Garment Bags: These bags are designed to protect clothing items during storage or transportation. They are typically long and narrow, allowing garments like dresses, suits, or coats to be hung inside. Garment bags may feature a zipper closure and are often made from clear polyethylene material for easy visibility.
