Why Choose Our Heat Seal Bags
Custom Heat Seal Bags | Hermetic Sealing for Food, Medical & Industrial Packaging
Heat seal bags are sealed using thermal bonding — the application of heat and pressure to the bag's sealant layer, fusing the film surfaces together to create an airtight, hermetic seal. Unlike zipper or adhesive closure bags, heat-sealed bags provide tamper evidence (the seal must be broken or cut to access the contents) and airtight integrity that mechanical closures cannot guarantee — making heat sealing the standard closure method for food preservation, pharmaceutical packaging, and medical device sterile barrier applications.
Heat Seal Bag Applications
- Food Packaging: Airtight sealed snack bags, frozen food pouches, dried goods packages, and portion-controlled food sachets requiring hermetic sealing
- Medical Device Pouches: Sterile barrier heat-sealed Tyvek/film pouches for medical devices requiring long-term sterility maintenance
- Pharmaceutical Sachets: Unit-dose pharmaceutical packaging where hermetic seal integrity is critical for drug stability
- Industrial Parts: Heat-sealed VCI (vapor corrosion inhibitor) bags for metal parts requiring corrosion protection during storage and transit
- Sample Packaging: Heat-sealed sample sachets for cosmetic, food, and product sampling programs
Heat Seal Parameters
Effective heat sealing requires matching the sealing temperature, pressure, and dwell time to the specific sealant film and desired seal strength. Common sealant materials include LDPE (seals at 110–130°C), CPP (cast polypropylene, seals at 140–160°C for high-temperature applications), and LLDPE (enhanced strength seals at 115–135°C). Seal integrity is validated through peel strength testing and burst pressure testing.
Heat Seal Integrity: Why It Matters
A heat seal that fails in service is not just a packaging failure — it is a product failure. For food products, a broken heat seal exposes food to atmospheric oxygen, causing spoilage. For sterile medical devices, a seal breach compromises sterility and renders the device unusable. For pharmaceutical sachets, seal failure exposes hygroscopic drugs to moisture. Heat seal integrity validation — peel strength testing, burst pressure testing, and visual inspection for channel defects — is not optional for critical applications. We perform seal integrity testing on representative samples from each production run for medical and pharmaceutical packaging.
Tyvek Heat Seal Pouches for Medical Devices
Medical device packaging uses a combination of porous Tyvek (which allows sterilizing gas — ethylene oxide or steam — to penetrate while excluding microbial contamination) and impermeable film (which provides the oxygen and moisture barrier required for long-term sterility maintenance). The heat seal creates the sterile barrier at the pouch boundary. ISO 11607 requires that this seal be validated for strength, integrity, and shelf life maintenance through accelerated aging and real-time shelf life studies — a qualification process we support with material documentation and seal parameter certification.

Heat Seal Bags in Arizona — FAQs
What is the difference between a heat seal bag and a zip lock bag?
Heat seal bags are permanently sealed using thermal bonding — the seal must be cut or torn to access the contents, providing tamper evidence. Zip lock bags use a mechanical closure that can be opened and resealed without permanent bond breaking — suitable for reusable applications but providing no tamper evidence. Heat sealing provides superior airtight integrity; zip locks provide consumer convenience for multi-use applications.
What temperature does heat sealing require?
Sealing temperature depends on the sealant film. LDPE seals at 110–130°C. LLDPE seals at 115–135°C with enhanced strength. CPP (cast polypropylene) seals at 140–160°C and is used for applications requiring boil-in-bag or retort compatibility. All temperatures refer to jaw temperature on the heat sealer — actual film temperature at the seal interface is lower by 10–30°C depending on film thickness and dwell time.
What is a Tyvek heat seal pouch?
Tyvek pouches use DuPont Tyvek on one side (the porous side that allows sterilizing gas penetration and is peelable for sterile field access) and clear film on the other side (the transparent, impermeable side for product visibility and barrier). The Tyvek and film sides are heat-sealed together at the pouch perimeter. ISO 11607 governs the design, validation, and quality system requirements for medical device sterile barrier Tyvek pouches.
What are VCI bags?
VCI (vapor corrosion inhibitor) bags contain chemicals that vaporize within the sealed bag environment, adsorbing to metal surfaces and creating a molecular-scale corrosion-inhibiting film. VCI bags protect ferrous metals, copper, brass, and aluminum from corrosion during storage and transit — the metal surface inside the sealed VCI bag remains corrosion-free for 24+ months without requiring oil or grease treatment.
