A wide range of flexible polythelene bag solutions to suit every need.
Our polybags, which are converted on our bag machines from extruded polytube, can be supplied either loose in cartons or on perforated rolls for easy tear-off use. Custom manufacturing allows us to offer a wide range of design features including gusseted bags, bottom seal plastic bags, side seal plastic bags, die-cut handles and perforation holes as well as tinted, opaque or clear natural finishes. With our expertise and in-house production, the possibilities are endless.
Side seal bags, also known as side weld bags, are usually bags with a lighter gauge. They are produced from folded polyethylene sheeting which is sealed (or welded) on each side with a hot blade. Side seal welds can be produced on flat or gusseted bags offering low-cost versatility, perfect for many retail solutions. As the seals are located on the length of the bag on both sides, the finished bag has one top opening and a seamless bottom.
Benefits of a Side Seal Bag
- Bag opening can have a lip or backflip
- No seam on bag bottom
- Bag can have a bottom gusset
- Bag punches, holes, hang holes, and thumb notches are easily applied
Applications of Side-Seal bags
Bag with Bottom Gusset
General Purpose Bags
The ultimate heavy-duty and leakproof solution, bottom seal bags are manufactured by using high temperatures to seal the bottom of the bag which is then cut with a flying knife. Bottom seal bags are tubular in design, with the seal located at the bottom width of the bag. They are designed to withstand great stress on both the seal and sides, making bottom seal bags an ideal choice for the use of heavy materials.
