Custom Heat Seal Mylar Bags
Custom Heat Seal Mylar Bags are designed for applications requiring a secure heat-sealed closure. Their multilayer flexible construction can provide protection against moisture, oxygen, light, odors, and external environmental exposure when the appropriate material structure is selected.
At Mylar Bags Pro, we manufacture custom heat-sealable bags using PET, PE, aluminum foil, Mylar film, and other suitable laminated barrier structures.
Secure Heat-Sealed Closure
Heat sealing provides a strong closure when the bag material and sealing conditions are properly matched. Seal temperature, pressure, dwell time, and equipment should be validated for the selected material structure.
High-Barrier Protection
Selected high-barrier structures can help reduce exposure to moisture, oxygen, light, and odors. Barrier performance depends on the material construction and intended application.
Moisture & Oxygen Barrier
Appropriate multilayer films can help limit moisture and oxygen transmission, making them suitable for compatible products requiring additional environmental protection.
Light Barrier Options
Aluminum foil and other opaque barrier structures can help reduce light exposure for products that require light-sensitive packaging.
Food-Grade Material Options
Suitable food-grade material structures are available for compatible food packaging applications. Final material selection should be based on the product and applicable food-contact requirements.
Vacuum-Compatible Options
Selected heat-sealable structures can be engineered for compatible vacuum packaging applications. Vacuum and seal performance should be tested with the final product and equipment.
Custom Sizes & Shapes
Heat Seal Mylar Bags can be manufactured in custom dimensions and shapes according to product volume, filling requirements, sealing equipment, and desired presentation.
