Rizhao Luming Plastic Technology Co., Ltd. is a professional manufacturer focused on HDPE Inner Packaging Bags, providing reliable food-grade packaging protection for various industrial and agricultural products. Our company owns a 16,500 ㎡ standardized production workshop and more than 100 sets of advanced production equipment, with a stable monthly output of hundreds of millions of finished bags to fully meet global customers' bulk ordering demands.
All our HDPE Inner Packaging Bag adopt premium food-grade raw materials, featuring high tensile strength and excellent moisture barrier performance. Standard sizes are perfectly compatible with most mainstream turnover containers. Backed by a team of over 120 skilled workers and mature production technology, we support large-volume customized orders with stable quality and competitive factory pricing, tailoring exclusive packaging solutions for different customer scenarios.

High-Density Polyethylene is a high-performance packaging material specially adapted to complex industrial and agricultural packaging environments, with durability and structural stability. The material density ranges from 0.941–0.965 g/cm³, forming a sturdy and tough film structure that effectively resists tearing and damage under heavy load conditions.
This material boasts far better moisture vapor barrier performance than ordinary polyethylene materials, effectively isolating external humidity and preventing moisture damage, clumping and quality deterioration of sensitive products during long-term transportation and storage.
In addition, our HDPE materials have passed professional food-grade certification, fully complying with international food hygiene standards. The finished bags have no peculiar smell and zero contamination risks, safely supporting direct contact with edible products and completely protecting product quality and safety.

Lining HDPE Inner Packaging Bags inside turnover baskets, cartons and storage barrels can effectively keep the inner wall of containers clean and hygienic. It greatly reduces the frequency of container cleaning, saving customers a lot of water resources and manual labor costs in daily operation.
The thin but high-strength film structure fits perfectly with various container shapes without increasing extra packaging volume. Standard sizes are widely applicable to conventional turnover containers for fruit and vegetable distribution and food processing industries.
Supported by our super-large monthly output, bulk orders can effectively reduce unit packaging costs. We maintain a stable and sufficient supply chain all year round, helping large-scale purchasers achieve cost reduction and efficiency improvement in packaging links.

Our HDPE inner packaging bag have strong industry compatibility and can meet the packaging and protection needs of multiple scenarios:
Agricultural Industry: Used for lining harvest crates and storage bins, protecting fruits, vegetables and root crops from friction and damage caused by rough container surfaces during picking, transportation and turnover.
Food Processing Industry: Applied to box-in-bag packaging systems for raw material storage, effectively isolating grains, powder raw materials and frozen food from external pollution, maintaining long-term product purity in warehouse storage.
Hardware Manufacturing Industry: The excellent moisture barrier property provides a dry storage environment for metal parts, effectively avoiding rust and oxidation of hardware accessories during storage and transportation.
Chemical Industry: Custom anti-static models are available for safe packaging of explosive powder materials, and high-barrier specifications can prevent deliquescence and deterioration of hygroscopic chemical raw materials exposed to air.

We provide customized packaging that is a one stop solution for your container size, load weight and operating circumstances.
Anti-fog ingredients keep film clean for quick visual examination without opening bags. Thickness may be tweaked: thick film for robust items; thin film for light produce to balance protection and cost.
Full-process QC assures conformity with international standards. Heat seals are tested to ASTM F88 to prevent leakage under maximum loads.
ASTM D1709 dart tests show puncture resistance. Full thickness screening eliminates weak spots to prevent packing failure.
For export inspections, we can provide batch certifications and complete traceability data to show compliance with food-contact and industrial packaging regulations.

Q1: What are the advantages of HDPE inner bags compared with LDPE bags?
A1: HDPE material has higher tensile strength and better moisture barrier performance under thinner thickness, which can provide more stable protection for hygroscopic and sensitive materials and effectively reduce packaging material consumption.
Q2: Are these HDPE bags suitable for hot filling production?
A2: Yes. The product can withstand a high temperature of 110°C for stable use. We suggest testing the sealing performance according to your actual product temperature and load conditions to ensure optimal use effect.
Q3: How to solve static electricity risks during powder filling?
A3: We add professional anti-static additives in the extrusion production process to reduce the surface resistivity of the film, meeting the anti-static safety standards for flammable and explosive powder packaging.
Q4: Are these HDPE inner packaging bag recyclable?
A4: Yes. The product belongs to #2 recyclable HDPE plastic, which is widely accepted by industrial recycling systems and conforms to green environmental protection and circular economy development requirements.
Q5: What is the valid storage period of the bags?
A5: Stored in cool, UV-proof and dry conditions, the bags can maintain stable physical properties for 2-3 years. We recommend using them within 12 months to ensure the best sealing and barrier performance.
