3 Side Seal Pouches
Polymaven’s three side seal pouches are the industry’s go-to format for efficient, protective packaging. With seals on three sides and one open end for filling, they provide excellent barrier properties and versatility across food, pharmaceuticals, and personal care sectors.
What Is the 3 Side Sealed Pouch
made from?
Every 3 side sealed pouch combines multiple layers that balance flexibility, strength, and product protection. Take a look at the materials we recommend - each chosen for performance, durability, and shelf appeal.
Foil 3-side-seal pouches provide the strongest shield against light, moisture, and oxygen. They’re the go-to for coffee, powdered supplements, and any product where freshness is non-negotiable.
Metalized polyester
MET-PET film delivers a sleek, metallic finish with high barrier protection at a lower weight than foil. It’s ideal for snacks, dry goods, and products that need long shelf life with premium shine.
Polyethylene terephthalate
PET 3 side seal pouches are strong, glossy, and brilliant when printed - the classic outer layer for vibrant branding and a premium look. Their heat resistance and durability make them a packaging staple.
Biaxially Oriented Polypropylene
BOPP pouches are smooth, clear, and durable, showing off your product while resisting wrinkles and tears. Perfect for snacks, cereals, and dry foods that need clarity and structure.
Polyethylene (sealant layer)
As the reliable inner layer for most laminations, PE film brings flexibility and seal strength to your 3 side seal. It’s tough, food-safe, and ideal for creating leak-proof seals on liquids, frozen goods, and fragile products.
Polypropylene/
Monomaterial
PP 3 side seal pouches maintain their shape under heat and weight, making them ideal for heavier or structured products. They offer a crisp, refined finish and strong recyclability potential.
Ethylene Vinyl Alcohol Copolymer
EVOH provides an advanced oxygen barrier while staying lightweight and transparent. It’s ideal for food and liquid packaging that demands freshness and recyclability.
Nylon holds strong against punctures and toughness - perfect for sharp or heavy contents. It’s a key layer in vacuum and retort pouches that need to withstand heat, pressure, and handling.
Kraft 3-side-seal pouches bring a natural, textured finish that eco-minded brands love. Layered with film for barrier protection, they’re perfect for organic snacks, teas, and artisanal products.
Vacuum packaging
Nylon brings the muscle and PE brings the seal. They’re a reliable combo for vacuum 3-side-seal pouches that need to hold strong from packing to storage.
