HDPE Produce Liner Bags

HDPE Produce Liner Bags for Fresh Produce Protection – Food-Grade High-Density Polyethylene Container Liners

Rizhao Luming Plastic Technology Co., Ltd. is a professional manufacturer the production of HDPE Produce Liner Bags with virgin high-density polyethylene raw materials. Covering a modern production plant of 12,000 square meters and equipped with more than 100 sets of advanced production equipment, our factory can supply hundreds of millions of agricultural packaging products every year to meet global market demand.

All our food-grade container liners feature a uniform film thickness ranging from 15 to 80 microns and a density of 0.941 to 0.965 g/cm³. With excellent puncture resistance certified by ASTM D1709 drop test standards, our integrated R&D and production system delivers stable and reliable quality, making these HDPE Produce Liner Bag the ideal packaging solution for fresh produce transportation and storage.

Premium Material Construction for Food Safety

Fresh agricultural products require high-standard food-contact packaging, and our liner products fully meet global safety certification requirements. We adopt 100% virgin HDPE resin that complies with FDA and EU 10/2011 food-contact regulations, with no recycled materials or harmful additives added during production.

The molecular structure of high-density polyethylene forms a tight protective barrier against external moisture, dust and various contaminants. This material is naturally resistant to agricultural residues and chemical pollutants, effectively avoiding product contamination during sorting, packaging and transportation. Different from recycled plastic liners, virgin HDPE raw materials completely eliminate the risk of unknown substance migration, fully protecting produce freshness and end-consumer safety.

Barrier Properties for Extended Shelf Life

Moisture loss is a core problem leading to fresh produce quality degradation and weight loss in the logistics process. Our HDPE Produce Liner Bags container liners boast excellent moisture vapor barrier performance, effectively inhibiting the transpiration of fruits and vegetables, and maintaining stable turgor pressure of agricultural products throughout the entire supply chain.

The micro-closed environment formed inside the liners can scientifically adjust the exchange of oxygen and carbon dioxide, avoid anaerobic respiration caused by gas imbalance, and greatly reduce the rate of produce spoilage. Multiple field verifications show that packaging with our liners can extend the shelf life of fresh produce by up to 30% compared with ordinary unlined packaging, effectively reducing commodity loss and improving corporate economic benefits.

Multi-Industry Application Solutions

These professional container liners are widely used in fresh produce export, food processing, cold storage and other scenarios, solving multiple packaging pain points for bulk logistics enterprises. In cross-border sea freight, ordinary cartons are prone to moisture absorption and structural damage during long-distance transportation. Our liners can form a stable protective layer for cartons, effectively protecting citrus, stone fruits, tropical fruits and other bulk produce from packaging collapse and moisture damage.

In industrial food processing and field collection operations, large-size liners can be placed in reusable plastic containers to separate different product batches, realize full-process traceability, and prevent cross-contamination of different vegetable and fruit varieties. For cold storage environments with low temperature all year round, ordinary packaging bags are easy to brittle and crack, while our customized HDPE liners maintain good flexibility and structural stability at 0°C to 4°C, avoiding produce skin shriveling and quality decline caused by cold air drying.

Special Needs Custom Features

We make sure that the micro and macro perforation is done to suit the respiration of the produce to allow correct gas exchange and to avoid rotting. Standard farm crate, bulk bin and carton sizes are provided for rapid delivery; bespoke sizes are available. With multi-colour printing you can brand and label products. Optional food-safe anti-block additives prevent film from adhering in humid settings for easy human and automated packaging.

Manufacturing Excellence & Quality Assurance

We operate film blowing and bag producing equipment out of our facility with around 120 employees. Full-process QC examines thickness uniformity, seal strength and material stability. Each batch is puncture and load tested to satisfy international logistical requirements. Eight local service centers to provide timely technical help. Our experts offer customized consultation and sample to identify the best thickness, perforation and sealing options.

Circular Economy & Environmental Responsibility

Our liners are recyclable HDPE Code #2, which is compatible with recycling streams worldwide. Downgauged HDPE provides the same protection as thick LDPE but with less raw material and less plastic waste. Durable HDPE avoids breaking in use; spent liners are repurposed into new plastic items supporting green audits and sustainability reporting.

Frequently Asked Questions

Q1: How do HDPE and LDPE liners differ?
A1: HDPE is stronger and less permeable to moisture at lower gages. This allows for a lower unit cost and less plastic. Its stiffness means it's easy to use on high-speed packaging lines.

Q2: Ventilation via custom perforations?
Yes, there are micro and macro holes. We design the hole patterns to match the respiration of the fruit and to prevent anaerobic spoiling.

Q3: How to prevent liners from clinging to one another?
A3: Food-grade anti-block and slide additives are used during extrusion for easy separation in humid packing settings.

Q4: Are HDPE liner products recyclable?
A4: Yes. Code #2 HDPE is 100% recyclable and suitable with recycling systems worldwide to promote your green branding.

Q5: Maximum load capacity?
A5: Up to 22.7kg depending on thickness and kind of seal (flat or star seal). Performance for actual logistics is confirmed by drop testing.
