Pillow pack
The go-to format for flow wrapping — compact, cost-efficient, and versatile. Suitable for everything from snack foods to medical products.
Gusseted pack for taller items
Need extra vertical space? This format fits bulkier or higher-profile products without sacrificing seal strength or shelf appeal.
Euro hole and hang hole punch
Ideal for retail displays. Adds hanging functionality for pegboards — commonly used in snack packaging, hardware, and promotional sample packs.

Straight-cut seals
Delivers a clean, polished finish. A preferred choice for premium items where presentation is key, such as chocolates or beauty products.
Zig-zag cut
Fun and functional. The wavy edge adds visual flair and makes it easier for consumers to open. Great for grab-and-go items or kids’ products.
Tear notch
Designed for easy opening — no scissors needed. Perfect for single-use pouches, snack packs, or portable medical applications.
Horizontal seal serrations
The standard end-seal format in flow wrapping. Serrations run across the package’s width, ensuring consistent pressure, predictable tear behavior, and a familiar aesthetic. Commonly used for snacks, baked goods, and everyday CPG items.
Vertical seal serrations
Serrations run lengthwise, giving the package a modern, premium look. Offers more directional control when tearing and is ideal for slim or upscale products. Requires a tailored sealing jaw setup.
