Rizhao Luming Plastic Technology Co., Ltd. manufactures Heavy Duty Large Black Trash Bags engineered from premium‑grade polymers to deliver exceptional durability and reliability. With over 100 sets of advanced production equipment, our 12,000 m² manufacturing facility produces hundreds of millions of units monthly, ensuring consistent quality and stable supply. Our Black Trash Bags feature thickness ranging from 1.2 to 3.0 mil, with puncture‑resistant construction and reinforced heat‑sealed bottoms. Backed by a team of 120+ professionals and nationwide service through 8 direct‑operated stores, we deliver enterprise‑level waste management solutions trusted by commercial kitchens, construction sites, and industrial facilities across global markets.

Your waste containment system needs bags that will not fail under strain. Our bags are made from a blend of Linear Low-Density Polyethylene (LLDPE) and HDPE that gives a flexible yet very robust film structure. The stretch qualities of this blend of fabrics also help to eliminate the zipper effect when the surface is hit by sharp objects.
The high-performance polymer mix has excellent tensile strength properties in the longitudinal and transverse axes. You will be dealing with heavy construction material, damp biological detritus and sharp metal shards without worrying about rips or punctures. Each bag is precisely extruded to provide equal thickness across the whole surface thus avoiding weak areas that lead to early failure.
We have a virgin resin mix that is odor free, yet gives you the durability you require. The material stays flexible under stress, molding to unusual forms, while yet preserving its structural integrity throughout collection and transport.

Bags are needed on construction and demolition sites that don’t compromise on handling the jagged materials. Our Heavy Duty Large Black Trash Bags securely hold up drywall pieces, scrap wood with exposed nails, shattered tiles, and metal debris. The high mil thickness avoids punctures from sharp edges and the huge capacity minimizes the frequency of bag changes, decreasing your labor expenses.
Food processing facilities and commercial kitchens must have leak-proof performance to meet sanitary requirements. You’ll be comfortable handling heavy, moist organic garbage and sharp food scraps like bones and shells. The bags remain intact even when loaded with liquid-saturated garbage, minimizing messy leaks during transit.
Industrial storage and industrial facilities produce substantial waste streams.
Our Black Trash Bags are compatible with plastic strapping, pallet wrap and metal shavings. Their opaque surface makes them seem clean and professional.
Property management businesses, hotels and sanitation services may buy in bulk to save money and have confidence. Available in many sizes to accommodate a variety of containers, from the typical office bin to the larger outdoor receptacle.

Each batch undergoes rigorous quality inspections. Puncture resistance is confirmed by Dart drop impact testing (ASTM D1709). Elmendorf tear tests (ASTM D1922) measure tear propagation Seal strength tests confirm that seals withstand rated loads without cracking.
Water leak testing guarantee liquid tightness. Micrometers verify thickness equals given mil specifications. We utilize virgin resin only to achieve consistent performance. Heavy durable black garbage bags are all manufactured to worldwide industrial performance requirements.
Direct manufacturer price no intermediary markup better value for your budget Huge monthly production for constant supply, with added savings on bulk purchases.
Our combined R&D, manufacturing and sales team provides a quick service with consistent quality, based on years of packaging knowledge.
Large manufacturing capacity for timely delivery, nationwide distribution. Standard sizes or bespoke packaging are available to meet your trash disposal requirements.

Q: What is the difference between Mil and Micron for Black Trash Bags?
A : Mil is a unit of measure for high duty uses and is equal to 1 / 1000 of an inch . Microns often denote lightweight liners . Heavy duty bags should be measured in Mils for best puncture resistance and dependable service.
Q: Why is Star Seal for big loads?
A. The star seal presses the plastic together in one spot at the bottom and makes numerous layers of film. This design provides far better leak prevention and weight distribution than flat seal construction and will not blow out under heavy loads.
Q:Can these bags be kept outside?
A: Yes, it’s naturally UV resistant because of the high carbon black content, so the plastic won’t become brittle from sun exposure. This makes them perfect for outdoor rubbish collection locations and temporary storage places.
Q: Can these bags be used for sharp waste?
A: They provide great containment integrity and puncture resistance, however users should verify local requirements for particular waste kinds. They are the preferable solution for sharp non-regulated garbage because of their opacity and structural robustness.
Q: How can I pick the thickness?
A: 1.5 mil offers dependable performance for common heavy trash. For sharp construction debris or heavy industrial metal trash, consider 2.0 to 3.0 mil bags for zero-failure performance under harsh situations.
