Frequently Asked Questions

1. What’s the difference between a heat sealer and a bag sealer?

A heat sealer applies heat to create an airtight seal on bags or poly film. Gateway offers handheld and pedestal sealers from 200mm to 800mm. A bag sealer can include tools like the Heat Sealer - 200mm with cutter or the Impulse Hand Heat Sealer - 600mm, which are perfect for sealing various bag types quickly and efficiently.

2. Is there a machine that can heat and seal at the same time?

Yes. Our Hooded Heat Shrink Machine (60600) is the ideal heat and seal machine. It combines sealing and shrinking in a single step, making it perfect for high-volume operations like wrapping boxes, bottles, and containers.

3. Can I use a heat sealing machine for laminated or foil packaging?

Absolutely. Our Pedestal Heat Sealers (300mm–800mm) are built for versatile film types, including polypropylene, polyethylene, and laminates. For added finish and shrink control, the Hooded Heat Shrink Machine is excellent when paired with shrink film, offering precision with its adjustable plate and automatic operation.

4. How is a heat seal machine different from a thermal sealing machine?

While both use heat, a thermal sealing machine usually refers to automatic or continuous systems. At Gateway, the Hooded Heat Shrink Machine is our thermal option — offering a full seal and shrink cycle, perfect for bundling and retail packaging, while the Pedestal Heat Sealer offers manual impulse sealing.

5. What is a bag heat sealer machine used for?

Our Impulse Hand Heat Sealer - 600mm and Heat Sealer - 300mm with cutter are perfect bag heat sealer machines, helping seal plastic bags, poly pouches, or tubing in seconds. For shrink applications, the Hooded Heat Shrink Machine can also shrink-seal entire bagged items for retail-ready results.

6. Can I use a bag sealing machine for heavy-duty packaging?

Yes. The Pedestal Heat Sealer - 800mm offers wide sealing for large or thick bags. For items that require both sealing and shrink-wrapping (like boxed or multi-product packs), the Hooded Heat Shrink Machine provides a professional-grade finish and protection.

7. What materials are heat sealable?

Gateway’s heat sealable machines support polyethylene, polypropylene, PVC shrink films, and laminates. For shrink wrapping, use the Hooded Heat Shrink Machine, which is compatible with PVC Heat Shrink Films and wraps aerosols, bottles, and product kits with ease.

8. Can I seal pallet shrink wrap with a heat sealer?

Not exactly. Traditional heat sealers aren't suitable for pallet shrink wrap because they’re designed for sealing flat poly bags or tubing. Instead, for wrapping and securing pallets or large bundles, Gateway Packaging offers heat shrink guns, such as the Ripack 2500 and Ripack 3000.

These gas-powered shrink wrap guns provide the high-intensity heat needed to shrink large-format plastic films tightly around pallets, offering durability, load stability, and tamper resistance. They’re ideal for warehousing, logistics, and export packaging.

If you're handling palletised loads or oversized items, our shrink wrap gas gun range is the safest and most efficient choice.

9. Is there a heat sealer and cutter combination machine?

Yes. Gateway offers Heat Sealers - 200mm & 300mm with cutter, perfect for creating custom-length bags. For shrink applications, the Hooded Heat Shrink Machine also cuts and shrinks in one operation — a great solution for display packaging.

10. Can I use a heat sealer for plastic bags?
Yes — but it depends on the type of plastic. Most standard polyethylene (PE) and polypropylene (PP) bags can be sealed using our impulse Heat Sealers ranging from 200mm to 600mm. These are perfect for light to medium-duty applications.

However, for thicker, multi-layer, or shrinkable plastic materials, a higher-powered solution like our Pedestal Heat Sealers or the Hooded Heat Shrink Machine is recommended. These machines provide stronger and more consistent sealing across complex or retail-ready plastic packaging formats.
