Poly bags are among the most common applications for poly sheeting. They can be used for a variety of things, including food packaging, small parts, and construction materials. Side Weld bags are created by stretching sheets of film to the specified length, then cutting and sealing them together to create a pouch.

Polyethylene and polypropylene are the two most prevalent poly bag materials. Polyethylene is the more popular of the two due to its versatility. Polyethylene bags come in a variety of densities, each with its own set of qualities, strengths, and applications. Polypropylene is also prized for its tensile strength and clarity. Let's look at the five most frequent forms of poly bags created from these two materials.

Bottom Seal Poly Bags

Bags with a bottom seal are seamless on the sides, have a top hole, and are sealed at the bottom. For heavy-duty applications, bottom seal bags are employed. They can be built to exact measurements, using high-quality materials and a wide variety of printing options. Watertight and leak-proof bags are examples of bottom seal poly bags.

Rolling Bags

Rolling bags are individually sealed and ready to be pull off the roll. Single wound sheeting, double wound sheeting, gusseted and centre slit gusseted tubing, wound open-end first or sealed-end first are available rolling poly bag options. 

Thumb Notches Poly Bags 

To make handling and removal of goods easier, poly bags often come with a semi-circular hole on the top of the bag, sometimes known as a "thumb notch." These are basically another type of bottom seal poly bags but easier to be carried.

Hanging Poly Bags 

Wicket, staple pack, hang hole, and door knob bags are just a few of the hanging poly bags.

Side Weld Poly Bags 

Instead of having seals on the bottom, side seal poly bags feature seals on the side. The bottom has a fold, the top has an opening, and both sides are sealed. They're best for light-weight items and can be less expensive than bottom-seal bags in some circumstances. 

What are side weld bags, how are they used, and how can they be customized? 

Because of their variety, cost-effectiveness, durability, and versatility, side weld bags are particularly popular in the retail sector. According to Reports and Data, the side weld bag market size will grow exponentially over the coming years. This seal (also known as a weld) is made from folded polyethylene sheeting that has been sealed on both sides and is perfect for use on flat and bottom gusset bags. Side weld bags are light to medium in weight and provide good general-purpose bags at a moderate cost.

Side weld bags contain only one hole, with the seal running the length of the bag on either side, resulting in a smooth bottom. They are available in a wide range of sizes, thicknesses, and substrates, and can include features such as euro slots, headers, and tear serrations. Other design elements, such as permanent or re-sealable tapes, can be added. They're perfect for security tape bags, mailer bags, and other custom poly bags that require an uneven opening.

This product starts out as a centrefold film, but after being heat-sealed on two sides, it only has one opening, generally at the top. Bottom gussets are inserted at the bottom section to offer another layer of volume filling and to "square-off" the bag's bottom. For packaging or display purposes, the bag can now be filled and stood up on its bottom.


  • There are numerous advantages to using side weld bags. These are the bags:

  • On the bottom, there are no uncomfortable seams.

  • It's possible that the bag's opening has a lip or a backflip.

  • Bag punches, holes, hang holes, and thumb notches are all easily accommodated.

  • Have a variety of clarity options, such as colorful, clear, or frosted plastic.

Conical tapering sleeves for V-shaped objects like men's ties, umbrellas, automobile wiper blades, and even pizza slices can be nicely accommodated into customized side weld bags.
