Rizhao Luming Plastic Technology Co., Ltd. produces heavy‑duty HDPE Carry Bags manufactured from high‑density polyethylene resin for load‑bearing performance. Based in Shandong, our 16,500 m² production site runs over 100 sets of advanced film‑blowing and bag‑making equipment, delivering hundreds of millions of finished units every month. Our HDPE Carry Bag feature one‑piece blown‑film construction for full‑body integrity, plus widened reinforced handles rated for 5‑35 kg loading capacity. All raw materials meet food‑grade direct‑contact safety standards. Backed by 120+ skilled production staff and mature manufacturing workflows, we maintain stable quality for large‑volume orders and offer full customization for size, thickness and printing.

High density polyethylene carrier bags are a high performance packaging alternative based on linear molecular chains that provide good stiffness. Its crystalline structure gives it a strength to thickness ratio that low density polyethylene cannot equal.
This trait enables us to lower the film gage while maintaining durability. So the buyer benefits from reduced shipping weight and cheaper unit cost, but still guaranteed puncture resistance for items with sharp edges.
Due to their inherent moisture-barrier properties and chemical inertness, these bags are ideal for various working situations. Whether you work with frozen food or industrial-grade supplies, the polymer retains its mechanical qualities throughout vast temperature ranges.
| Property | Specification | Test Standard |
|---|---|---|
| Density Range | 0.941–0.965 g/cm³ | ISO 1183 |
| Tensile Strength | 20–30 MPa | ASTM D882 |
| Melting Point | ~130°C | DSC Analysis |
| Melt Flow Rate | 0.2–1.0 g/10 min | ASTM D1238 |
| Dart Impact Resistance | ≥200 g | ASTM D1709 |
| Elongation at Break | 400–600% | ISO 527 |

These bags are used in retail supermarkets for bulk canned and pre-packed items. Reinforced vest handles properly distribute weight and withstand tearing.
Chemical and fertilizer suppliers prefer HDPE Carry Bags. Bags with Strong environmental stress fracture resistance Resistant to strong chemicals.
Cold-chain operators utilize them for frozen products. HDPE is flexible and robust at sub-zero temperatures and fulfills FDA food-contact guidelines.
Food processors need dust and moisture protection. The one-piece construction is seamless, with no holes for pollutants to get in.

Every production batch completes dart impact testing following ASTM D1709. This test simulates real‑world drop impact by measuring the force needed for a weighted dart to pierce the film.
Tensile‑strength and elongation testing per ISO 527 verifies breaking‑load performance. You receive bags that will not rupture when filled up to their rated capacity.
Heat‑seal‑strength tests under ASTM F88 match bottom‑seal performance to film strength, avoiding seam separation under heavy‑load stress.
Gauge‑variance inspection guarantees uniform thickness across full production runs. Consistent material performance delivers predictable results inside automated packing equipment.
Coefficient‑of‑friction testing optimizes bag opening performance for busy checkout counters. Balanced slip‑surface properties help staff separate bags quickly with minimal downtime.

Our 12,000 m² manufacturing site supports full customization on dimensions, film gauge and printing. Whether you need compact 5 kg bags for convenience‑store use or heavy‑duty 35 kg carriers for wholesale workflows, we tailor products for your operating conditions.
Thickness adjustment enables cost‑saving down‑gauging solutions. Reduce micron thickness while retaining target load performance, cutting both material cost and total shipping weight.
Multi‑color flexographic printing turns plain carriers into walking brand media. HDPE matte surface accepts printing ink cleanly for sharp, vivid graphics that boost your retail visibility.
Multiple handle reinforcement styles are available: die‑cut, soft‑loop and patch handle options. Our team will suggest the best punch‑out style based on your typical load weight and end‑user handling habits.

Q1: Why do HDPE Carry Bag produce a crinkly sound compared to LDPE alternatives?
A1: This comes from high resin crystallinity, which delivers the stiffness and strength characteristic of HDPE bags.
Q2: Can I down‑gauge these bags to lower overall costs?
A2: Yes. HDPE’s high tensile‑strength allows thinner‑gauge films that outperform thicker LDPE equivalents.
Q3: Are HDPE Carry Bag recyclable?
A3: Yes. They fall under SPI Resin Code 2 and are among the most widely mechanically‑recycled plastic materials worldwide.
Q4: How do you stop handles from tearing under heavy‑load conditions?
A4: We use reinforced punch‑out structures and maintain balanced molecular orientation throughout the extrusion process.
Q5: Do these bags offer UV‑resistance for outdoor‑exposed applications?
A5: HDPE has better natural UV‑resistance than many polymers. We can add dedicated UV‑stabilizer additives for long‑term outdoor usage to prevent material degradation.
