Food-Grade Bags: Details That Affect Line Speed and Shelf Presentation

Food-grade bags are often judged by shelf appearance, but the package has to perform long before it reaches the customer. Resin selection, bag style, venting, handles, microperforation, seal behavior and line speed can all affect the final result.

The best specification includes the food type, dimensions, equipment, seal method, desired appearance, print requirements and whether the bag is individual, wicketed or form-fill-seal.

Small details can have large production consequences. Vent placement, lip dimensions, wicket hole location and film stiffness can influence how smoothly a bag opens, fills and seals.
