When shaped holes in plastic film are mentioned, food packaging is usually the first application that comes to mind: produce bags, counter display packs and hanging bags. Yet many applications come from sectors with little connection to food: agriculture, construction and automotive. Here, the hole rarely serves to let the product breathe. It serves to carry it, hang it, open its packaging or lay the film on the ground. Each function requires a precise geometry, in the right position, repeated consistently over thousands of metres of film. This article looks at the shapes and patterns used in the main non-food markets, how they are designed and which process choices matter when industrial perforation is integrated into a converting line. What shaped holes are and how they differ from round holes A shaped hole is any opening with a non-circular geometry or designed for a specific function. Common examples include handle [...]

Anyone who handles stretch film mini-roll production for manual use knows: it's not just about rewinding smaller. The compact format — typically between 10 and 12.5 cm in height — brings challenges that don't show up as often on pallet-roll rewinding: irregular opening tails, waste concentrated at roll changes, tension that varies from one core to the next. For production managers, every defect on the mini-roll becomes visible to the end user the moment they try to open it. In this article, we look at the most common problems — tails, waste, breakage — and the technical solutions that optimize cycle time and quality. Why Mini-Rolls Are More Delicate Than Standard Rewinding The mini-roll is a low-height stretch film format — typically between 10 and 12.5 cm — designed for manually wrapping small, loose, or irregularly shaped items. You'll find it in auto repair shops, warehouses, spare parts counters, retail [...]
