I. Material Structure and Characteristics of Aluminum foil vacuum packaging Bags for Equipment

Aluminum foil vacuum packaging bags for equipment are typically made of multi-layer composite materials, including an aluminum foil layer (AL), a polyester layer (PET), a nylon layer (NY), and a polyethylene layer (PE). Each layer of material performs a specific function in the bag, providing multiple layers of protection.

Outer Layer (PET or Nylon)

Mainly used for printing and enhancing mechanical strength, ensuring the bag's resistance to friction and compression. The PET layer allows for high-definition printing of company logos, model numbers, and precautions, while the nylon layer improves the bag's puncture resistance.

Middle Layer (Aluminum Foil Layer)

The aluminum foil is the core functional layer of the bag, effectively blocking air, water vapor, light, and odors, ensuring that the equipment is not affected by oxidation or moisture during transportation and storage.

Inner Layer (PE or CPP)

As the heat-sealing layer, it ensures a tight seal at the bag opening and provides good flexibility and heat-sealing performance, suitable for vacuum evacuation and high-temperature sealing operations.

Functional Composite Layer (Optional)

For special industrial equipment, anti-static, UV-resistant, or high/low-temperature resistant film layers can be added to meet the packaging needs of different equipment in complex environments.

This multi-layer composite structure gives aluminum foil vacuum packaging bags for equipment excellent performance in terms of protection, sealing, and aesthetics.

II. Performance Advantages of Aluminum Foil Vacuum Packaging Bags for Equipment

Aluminum foil vacuum packaging bags for equipment are widely used in industrial equipment packaging, mainly due to their comprehensive performance advantages:

Excellent Barrier Properties

The aluminum foil layer almost completely blocks air and moisture, preventing metal parts from rusting, electronic components from getting damp, and precision instruments from oxidizing, thus improving the safety of equipment storage and transportation.

Strong Vacuum Sealing Capability

The inner heat-sealing film ensures that the bag opening is completely sealed. Vacuum evacuation removes air from the bag, further reducing the risk of oxidation and moisture, and minimizing shaking and collision of the equipment during transportation.

Anti-static and Anti-pollution

Anti-static films or coatings can be added to effectively protect electronic equipment and precision instruments, preventing electrostatic damage or dust contamination. High Mechanical Strength and Puncture Resistance

The multi-layer composite structure enhances the bag's tear and puncture resistance, maintaining its integrity even when loading sharp or heavy equipment.

High and Low Temperature Resistance and Chemical Corrosion Resistance

The aluminum foil composite film remains stable in environments ranging from -40℃ to +120℃, suitable for sea transport, cold chain logistics, and high-temperature processing conditions, while also preventing chemical corrosion damage to equipment.

Environmentally Friendly and Recyclable

Modern aluminum foil vacuum packaging bags for equipment prioritize environmental protection in material selection, using separable composite layers or biodegradable materials to achieve green packaging.

III. Production Process of Aluminum Foil Vacuum Packaging Bags for Equipment

High-quality aluminum foil vacuum packaging bags for equipment require a precise production process, including material lamination, bag making, and quality inspection:

Material Lamination

Through dry lamination or extrusion lamination processes, materials such as PET, aluminum foil, and PE are laminated into a multi-layer composite film. The amount of adhesive, temperature, and tension must be controlled during the lamination process to ensure uniform bonding of each layer.

Curing Treatment

The composite film is left to stand under constant temperature conditions to ensure complete curing of the adhesive, improving the adhesion and mechanical strength of the composite layers.

Printing and Slitting

The outer PET film can be color printed to display company logos, product models, and precautions; then it is slit according to size requirements to prepare rolls or semi-finished products.

Bag Making Process

Automatic bag making machines are used for three-side sealing, four-side sealing, or gusseted bottom sealing to form self-standing structures or ordinary flat bottom bags.

Quality Inspection

Strict testing is conducted on sealing performance, tensile strength, puncture resistance, and heat seal strength to ensure stable performance of each batch of products.

IV. Application Scope of Aluminum Foil Vacuum Packaging Bags for Equipment

Aluminum foil vacuum packaging bags for equipment can be used for packaging various industrial equipment and accessories.  Main application areas include:

Mechanical Equipment Parts

Bearings, gears, hydraulic components, metal screws, etc., are prone to moisture or oxidation during transportation. Vacuum Aluminum Foil Bags can prevent rust and deterioration.

Electronic Components and Precision Instruments

Chips, circuit boards, sensors, etc., are susceptible to moisture, static electricity, or dust contamination. Anti-static aluminum foil vacuum bags provide complete protection. Metal Materials and Powders

Including alloy powders, powder metallurgy materials, and precision castings, vacuum packaging can extend the storage life of materials and maintain stable performance.

Export Equipment Packaging

Sea or long-distance transportation requires high standards for packaging in terms of moisture resistance, salt spray resistance, and protection against mechanical shock. Aluminum foil vacuum bags can ensure that the equipment arrives safely at its destination.
