HDPE Liner Bag

HDPE Liner Bag for Industrial Containers – High-Strength Moisture Barrier Solution

Rizhao Luming Plastic Technology Co., Ltd. is a professional manufacturer specializing in industrial packaging solutions. We focus on the production of premium HDPE Liner Bag products, which are perfectly tailored for industrial containers, turnover boxes and carton packaging scenarios. Our factory covers an area of 12,000 ㎡, equipped with more than 100 sets of advanced film blowing and bag-making equipment, supporting a monthly output of hundreds of millions of finished products with stable and sufficient supply.

Material Composition and Barrier Performance

We exclusively adopt virgin-grade HDPE resin to produce every HDPE Liner Bag, ensuring zero impurity contamination and odor-free use. The product features a high-density molecular structure with a density range of 0.941 to 0.965 g/cm³. Compared with ordinary low-density polyethylene materials, it boasts far lower moisture vapor transmission rate and more reliable barrier performance.

This high-performance material forms a tight protective barrier that effectively isolates external dust, humid air and various environmental contaminants. It keeps agricultural products, industrial raw materials and other bulk cargo in pristine condition throughout long-term storage and cross-regional transportation, free from external environmental interference.

In addition, HDPE material has excellent chemical inertness, resisting most acids, alkalis and organic compounds. With strong multi-scenario adaptability, our liner bags can meet the packaging and protection needs of diverse cargo from fresh agricultural produce to industrial powder materials.

Technical Specifications

Engineered Strength for Demanding Operations

Our industrial liner bags are professionally engineered for heavy-duty use scenarios. The tensile strength can reach 30-40 MPa, with structural toughness, effectively resisting puncture and damage during frequent loading and unloading.

All products pass strict ASTM D1709 dart impact testing, which verifies stable impact resistance. Even when packaging sharp-edged materials, the bag body can maintain intact structure without cracking. The overall tear resistance is uniform, avoiding product leakage loss and production line shutdown caused by packaging failure.

The products feature a wide temperature adaptation range from -50°C to +80°C, maintaining stable physical properties in ultra-low temperature cold storage and high-temperature outdoor environments, with no deformation, brittle cracking or performance degradation.

Comprehensive Size Range and Customization Capabilities

We have a large inventory of standard-size liners, which are fully compatible with mainstream industrial turnover boxes and carton specifications in the market. Standardized size matching simplifies customer procurement procedures and shortens delivery cycles.

To meet differentiated packaging demands, we provide flexible thickness customization services. Customers can choose lightweight economical specifications for ordinary materials or heavy-duty reinforced HDPE Liner Bag grades for high-load and high-risk packaging scenarios.

We also support personalized dimension customization for special-shaped containers and exclusive application scenarios. Our professional engineering team provides one-on-one tailored solution design. Relying on 8 direct-operated stores across the country, we give priority to the production and delivery of bulk orders to ensure fast supply for global customers.

Food-Grade Safety and Hygiene Assurance

Our entire production process complies with strict food-contact safety regulations and fully meets FDA 21 CFR 177.1520 certification standards. The liners can be in direct safe contact with fresh fruits and vegetables, grains and food ingredients, widely applicable to food processing and fresh logistics industries.

The production workshop implements standardized cleanliness management. Each batch of products will undergo strict quality inspection, including heat seal strength test and overall air tightness detection, to eliminate leakage risks.

We adhere to the zero recycled material production policy, completely avoiding potential contamination risks brought by recycled raw materials. The odor-free and hygienic product features effectively protect product taste and quality, helping customers maintain brand reputation in the whole supply chain.

Cost-Efficiency Through Extended Container Lifespan

Using our container liner bags can effectively isolate cargo from the inner wall of turnover boxes, greatly reducing container cleaning frequency, saving a lot of manual labor and water resource consumption, and reducing daily operation costs for enterprises.

Avoiding direct friction and contact between goods and containers can significantly extend the service life of industrial containers, reduce the capital cost of frequent container replacement, and help enterprises achieve green and sustainable development goals.

In the process of multi-batch and multi-type cargo turnover, only the liner needs to be replaced instead of overall container disinfection and cleaning, which effectively improves operational efficiency. At the same time, the dual protection of moisture resistance and anti-pollution greatly reduces cargo quality problems and customer compensation risks.

Frequently Asked Questions

Q1: What advantages does HDPE Liner Bag have over LDPE in moisture protection?

A1: HDPE material has higher crystallinity, which delivers much lower moisture vapor transmission rate. It provides more stable and reliable moisture-proof protection, making it more suitable for long-term storage and transportation of goods in humid environments.

Q2: Can the liner be customized for anti-static working conditions?

A2: Yes. We can add permanent anti-static agents during film extrusion production to effectively eliminate static electricity, preventing dust explosion risks during dry powder filling and meeting the safety requirements of special working environments.

Q3: What is the conventional thickness of industrial-grade liner bags?

A3: The conventional thickness range for industrial scenarios is 40-150 microns. We will recommend the most appropriate thickness specification according to your cargo type, load weight and usage environment to balance cost and protection performance.

Q4: Are these HDPE liners environmentally recyclable?

A4: Yes. The product is marked with Resin Identification Code 2, which is 100% recyclable. It is an eco-friendly packaging choice, perfectly adapting to the circular supply chain and corporate sustainable development plans.
