What is rollstock film used for?
Rollstock film feeds directly into automated packaging machines, forming bags, pouches, and wraps. It is commonly used in high-volume production environments where speed and consistency matter. The film is extruded in large rolls, which makes it easy to store and efficient to use.
What is the difference between Twinseal and Sideweld bags?
Twinseal bags have seals along both sides, adding extra strength for heavier products or applications where the bags experience more stress. Sideweld bags are sealed on one side, offering a cleaner appearance and better stacking. Choosing the right option depends on your product's weight and how the bags will be handled.
How do I choose the right industrial packaging?
Start by considering your product’s weight, exposure to moisture, and handling during shipping and storage. From there, evaluate material strength, bag style, and the protection your product needs. A conversation with one of our packaging specialists can help streamline the decision-making process.
Do you offer custom-printed polyethylene bags?
Yes, we offer custom printed polyethylene bags with logos, product information, and compliance labeling. Our bags maintain their durability even with full-color graphics, making them perfect for branding while offering the strength needed for industrial environments.
