Poly Bags
Side Weld
Light-to-medium-duty poly bags sealed down both sides with a seamless bottom — a low-cost general-purpose bag.
What are side weld bags?
Side weld poly bags are light- to medium-duty bags made from folded polyethylene sheeting, sealed down the length of both sides. The bag has a single opening and a seamless bottom.
Cost-effective and versatile, they are one of the most common retail bags — also well suited to mailer bags, security tape bags, or any bag that needs an uneven opening.
