Advantages of Industrial PE rust-proof bags: High-Strength Material Protects Parts Integrity
Industrial PE rust-proof bags use high-density polyethylene (HDPE) or PE composite materials as their core raw materials. With their superior durability, moisture resistance, and rust prevention, they have become an ideal packaging solution for industrial parts and machinery components in sea, land, and cross-border transportation. These rust-proof bags combine physical and chemical protection, effectively reducing the risk of damage to parts during transportation and storage, ensuring the integrity and lifespan of the goods.
High-Strength Material Ensures Transportation Safety. Industrial PE rust-proof bags use thickened high-strength PE material, typically ranging from 0.08mm to 0.18mm in thickness, which can be flexibly selected according to the weight of the parts and transportation requirements. The bag body has excellent tear resistance, puncture resistance, and impact resistance, remaining intact even when faced with sharp metal edges or the squeezing and collisions during long-distance transportation. The material is highly flexible and does not easily crack in low-temperature environments, adapting to various environmental conditions in sea or land transportation, ensuring the safe arrival of parts at their destination.
Professional Rust-Proof Design Provides Long-Term Protection. Industrial PE rust-proof bags utilize VCI (Vapor Corrosion Inhibitor) technology, allowing rust-inhibiting molecules to be slowly released inside the bag and adsorbed onto the metal surface, forming a protective film that effectively isolates oxygen, moisture, and salt spray corrosion. The rust-proof effect can last for months to years, meeting the protection needs of long-term storage and long-distance sea transport. When used with a desiccant, internal humidity can be further reduced, enhancing moisture-proof performance and providing double protection against corrosion.
Multiple sizes and thicknesses are available to meet diverse part requirements. Industrial PE rust-proof bags support customization in various sizes and thicknesses, covering a full range of needs from micro-hardware parts to large mechanical parts. Smaller bags are suitable for packaging precision small parts such as screws, gears, and electronic components, while larger and thicker bags are suitable for high-value, large-sized goods such as mechanical parts and engine parts. Size tolerances are controlled within a reasonable range to ensure a tight fit between the bag and the part, preventing damage caused by movement or uneven stress during transportation.
Easy to use and improves packaging efficiency. Industrial PE rust-proof bags are lightweight and portable, easy to handle manually or mechanically, and support sealing methods such as heat sealing, tape sealing, or self-sealing strips, ensuring reliable sealing performance. The transparent material allows for quick identification of the parts inside, facilitating warehouse management and logistics inventory. Furthermore, parts only need to be cleaned and dried before packaging, requiring no complex processing, enabling fast and efficient packaging and greatly improving logistics efficiency.
They balance environmental protection and economy. PE rust-proof bags can be made from recyclable materials, meeting green production and environmentally friendly transportation standards. The lightweight material reduces transportation load and lowers logistics costs, while high strength and long-lasting protection reduce transportation damage rates, saving companies subsequent maintenance and parts replacement costs.
In summary, industrial PE rust-proof bags, with their high-strength and durable materials, professional rust-proof design, multi-size customization capabilities, and ease of use, provide a reliable, economical, and environmentally friendly end-to-end protection solution for metal parts and machinery accessories. They are particularly suitable for the high-standard protection requirements of sea, land, and cross-border transportation, making them an indispensable professional packaging product for modern industrial logistics.
Marine industrial PE rust-proof bags are professionally designed for the cross-border sea transport of hardware and machinery parts. They effectively address the challenges of high salt spray, high humidity, and bumps during sea transport. By providing dual protection through physical shielding and chemical rust prevention, these bags safeguard the integrity of parts throughout the shipping process. They are widely used for bolts, nuts, bearings, gears, machine tool components, and other hardware and machinery products.
In terms of material, the bags are made of high-strength high-density polyethylene (HDPE), with some upgraded versions using a PE-nylon composite structure. Thickness options range from 0.08 mm to 0.20 mm, allowing flexible adaptation to part weight and sharp edges. This material offers excellent tear and puncture resistance, protecting parts from sharp corners while remaining stable under extreme temperatures. The bags can withstand environments from -40°C to 80°C, resisting cracking at low temperatures and deformation at high temperatures to ensure continuous protection during transport.
The rust-prevention feature relies on integrated VCI (Vapor Corrosion Inhibitor) technology. Rust inhibitors inside the bag slowly release vapors that form a uniform protective film on metal surfaces, isolating parts from oxygen, moisture, and salt spray. Rust protection lasts 6 to 24 months, meeting long-term shipping and storage needs. Combined with reliable sealing through heat sealing, the bags maintain a stable internal anti-rust atmosphere. Using desiccants can further reduce humidity and enhance moisture protection.
For optimal performance, parts should be clean and dry before packaging to avoid oil residue affecting rust prevention. Bag dimensions should allow 10%-20% extra space for proper sealing. The lightweight design minimizes additional transport costs, and bags can be customized in different sizes to accommodate single parts or bulk packaging. Marine industrial PE rust-proof bags provide an efficient, reliable full-chain protection solution for hardware and machinery parts during sea transport.
Frequently Asked Questions (FAQs)
1. Can our Marine industrial PE rust-proof bags protect against seawater salt spray?
Yes, our rust-proof bags are made of high-strength HDPE or PE-nylon composite material, combined with VCI vapor phase corrosion inhibitor technology, effectively isolating oxygen, moisture, and salt spray. Even during long-haul sea transport, the high-salt environment prevents oxidation or corrosion of hardware parts and machinery components, ensuring the integrity of the goods.
2. How long does the rust-proof effect of the bags last?
The VCI rust inhibitor inside the bags slowly releases to form a protective film, typically providing rust protection for 6 to 24 months. Combined with heat sealing and desiccant use, the internal dry environment can be further maintained, meeting the long-term protection needs of long-haul sea transport and warehousing.
3. Can I customize the size and thickness of the rust-proof bags?
Absolutely. We support customization of various sizes and thicknesses, suitable for everything from small hardware parts to large machinery components. The thickness range is typically 8-20 microns, and the appropriate material and thickness can be selected based on the weight of the parts, their sharpness, and the transportation environment to ensure robust and reliable packaging.
4. What types of parts or accessories are suitable for rust-proof bags?
These rust-proof bags are suitable for bolts, nuts, gears, bearings, machine tool parts, and other metal hardware accessories. Thinner bags can be used for light parts and small accessories, while thicker bags are available for heavy machinery parts. Single-item or bulk packaging is supported to meet different warehousing and transportation needs.
5. What precautions should be taken when using rust-proof bags?
Before use, ensure the surface of the parts is dry, clean, and free of oil or impurities to guarantee rust prevention. Leave 10%-20% of the opening space when packaging; heat sealing or tape sealing will create a sealed space. It is also recommended to use a desiccant to further enhance moisture protection. Proper operation ensures the safety of parts throughout the transportation process.
