Rizhao Luming Plastic Technology Co., Ltd. has specialized in the development and mass production of Black HDPE Produce Liner Bags for agricultural cold-chain crates, cartons and bins. Our contemporary plant covers 16,500 m² and has more than 100 innovative machinery to produce hundreds of millions of agricultural packing goods each month. These liners are made of 100% virgin HDPE and food grade carbon black and also provide super light blocking, tensile and puncture resistance. They maintain containers clean by keeping out external light, moisture, dust and pollutants and safeguard fresh product throughout loading, transport and long-term storage.
HDPE has a stronger, denser molecular structure than regular LDPE liners to better perform in complex agricultural storage and transportation. Thin gage films have high tensile strength and can hold huge product loads without stretching or ripping, minimizing material costs while providing protection.
The FOOD GRADE BLACK PIGMENT blocks out almost 100% of light. It protects from light, prevents photosynthesis in potatoes, onions, ginger and other root crops, and prevents browning, sprouting and rotting, therefore increasing shelf life and maintaining market value.
Black HDPE liners also have very good chemical resistance. They oppose the organic acids and alcohols formed by maturing food, to prevent the film from breaking down. The lasting moisture barrier lowers water loss by respiration, stabilizes weight and quality of the produce and saves losses for the provider.

Our Black HDPE Produce Liner Bags are suited for comprehensive agricultural supply chain situations.
Root Vegetable Storage For bulk potatoes, onions and ginger. All shade prevents chlorophyll and sprouting, maintaining dormancy and reducing wastage.
Bulk Transport Protection Lining Wooden boxes and bins protect the goods from abrasion during handling, and reduce sales losses
Cross-Contamination Prevention: Disposable liners provide a sanitary barrier for reusable containers to prevent cross-contamination, save cleaning costs and increase bin service life.
Cold storage applications HDPE is resistant to embrittlement down to -50°C and is good for flash freezing, refrigeration and long cold chain transportation.
Gage Uniformity Test: Sampling of thickness eliminates weak regions and possibility of local rupture.
Seal integrity check: Heat seals are verified using air tightness testing. Star seals distribute the loading equally to avoid breaking and leaking of the seal.
Opacity Testing: The carbon black is checked for steady low light transmission and uniformity of shading.
Puncture resistance assessment: ASTM D1922 tear tests provide dependable resistance for sharp, stemmed product.
Standard sizes for popular containers. Custom sizes available.
Thickness options: Light leafy greens 10-15μm Heavy root crops and sharp produce 25-40μm
We provide custom logo printing and traceability codes.
We provide roll stock for automated lines and easy-open pre-cut liners for manual packaging.
Reduced unit packing cost with high strength-to-thickness ratio.
Excellent light blocking preservation increases shelf life and reduces spoiling losses to increase profit.
Liners keep moisture, dirt and residues out, reducing bin cleaning jobs and increasing the lifespans of reusable containers.

Q1: Why are black HDPE liners than transparent LDPE liners?
A1: Black HDPE liners completely block light to prevent crop sprouting and browning. Higher strength at thinner gages for cost savings and dependable protection.
Q2: Are these black HDPE production liners food contact safe?
A2: Yes. No hazardous migration. Made from FDA certified virgin HDPE and food grade carbon black. Compliant with worldwide food-contact regulations.
Q3: What is the practical benefit of the star seal design?
A3: The star seal distributes the weight of the product equally, minimizes concentrated tension and reduces the chances of bottom seal rupture and leaking.
Q4: Can these liners be used for ultra-low temp frozen storage?
A4: Yes. HDPE is still flexible and sturdy down to -50 deg C without becoming brittle, suitable for flash freezing and long term cold chain storage.
Q5: How do you determine the proper micron thickness for various produce?
A5: 10–15μm (light leafy greens), 25–40μm (heavy root crops, sharp-stemmed produce) for puncture and tear resistance.
