Manufacturing Process

The blended resins are then fed into extruders and melted at 380F. Screw drives, force the molten mixture through a precision die where air is introduced and a ‘bubble is formed’ This process is known as “blown film extrusion”.

Adjustments to wall thickness and diameter are made in this continuous bubble or tube. As it rises some 20 feet, it cools and is flattened and wound under tension into 50 – 200 lb. rolls. Our line-up of extruders gives us the flexibility to regularly produce custom film orders. This allows also for quick order fulfillment where tubing may be available in as little as 2 or 3 days.

From the extruders, the rolls of film are delivered to our print department. Flexographic stacked presses produce printed film in up to 6 colors with matte to gloss to metallic finishes. A smaller press does the less complex jobs such as produce roll bag printing and other I or 2 color jobs.

This versatility allows us to print small quantities of bags and also to handle huge press runs of a week or more. We can consistently meet deadlines while achieving consistent, quality results.

Either plain rolls from the extruder line or printed rolls form our presses are delivered to the bag making area of our plant. A myriad of sizes and options are available in essentially 3 types of bag conversion: single bags, bags on rolls (perforated tear-off) or bags on wire wickets.

Roll stock is loaded onto bag making machines where repetitive bottom seal or side seal converting takes place to produce individual bags from the large rolls Holes, vents, slits, perforations, handle punching, header sealing arc some of the many options available in each production run.
