Technical Specifications and Material Grade
Each ldpe polybag has flat measurements of 170 mm in width and 350 mm in length. The film thickness is precisely 50 microns, which equals 0.050 mm. This specific gauge provides a highly practical balance between flexibility and mechanical protection. It ensures the bag does not tear easily during manual handling or automated packing steps.
Virgin Polythene Construction
We manufacture these plastic bags using 100% virgin LDPE raw material. By choosing virgin polymer instead of recycled content, we ensure the material offers maximum clarity and consistent tensile strength. You won't find the off-odor, gray tint, or physical weak spots that are common with recycled regranulates.
Packaging Unit Details
This product is sold in cartons containing 500 pieces. Each single order unit contains one pack of 500 loose, flat bags. This makes it easy to distribute batches directly to assembly stations or packing benches.
Primary Industrial and Retail Applications
The 170x350 mm dimensions are well-suited for sorting and organizing longer, narrow products. Typical applications include:
- Packaging metal fasteners, bolts, and mechanical hardware kits.
- Grouping automotive spare parts, electrical cables, and wiring looms.
- Protecting assembly instructions, warranty leaflets, and technical manuals inside larger product boxes.
- Wrapping textile accessories, garments, and apparel items for e-commerce dispatch.
- Organizing plastic injection-molded components on assembly lines.
- Enclosing printed catalogs, corporate brochures, and promotional stationery.
Limitations and Exclusions
While this low density polyethylene bag is highly resilient under normal conditions, it is not suitable for all purposes. It should not be used for:
- Direct contact with food, pharmaceutical products, or medical devices, as it does not carry specific certifications for these industries.
- Heavy, highly jagged, or sharp metal shards that exceed the puncture resistance of a 50-micron film.
- High-temperature processes or hot-fill packaging lines.
- Heavy-duty construction waste or heavy rubble containment.
Handling, Sealing, and Performance
These transparent ldpe packaging bags offer high clarity, letting operators scan barcodes or inspect packed contents without opening the seal. When it comes to closing the bags, the virgin material is fully heat sealable. You can easily achieve strong, airtight closures using standard manual or automatic impulse sealers. They also work well with packaging tape, twist ties, or manual staples. The material resists tearing along the edges and retains its physical integrity under normal warehouse handling.
Selecting the Right Size and Gauge
If you pack objects with sharp edges or high weights, a thicker film range like 80 or 100 microns is often a safer choice. For lightweight items and general dust protection, however, this 50-micron (0.050 mm) bag is the standard, cost-efficient option. It reduces unnecessary plastic waste. The 170x350 mm size is ideal for elongated items. If your objects are wider than 150 mm, we recommend moving to our wider layflat dimensions to prevent overstretching the side seams.
Who Uses This Product
Our buyers for the ldpe-170x350 bag work across several different trades. Electronics manufacturers use them to group components for shipping. E-commerce fulfillment houses keep them in stock for quick accessory packaging. Automotive parts suppliers, logistics providers, and wholesale distributors rely on these bags to keep small inventory items clean and organized in storage.

Stoplast LDPE Polybag 170 x 350 mm
This 170x350 mm low density polyethylene bag is a flat, open-top plastic sleeve designed to protect industrial parts, textiles, and retail items during storage and shipping. Each polythene bag measures exactly 170 mm wide by 350 mm long. The film thickness is 50 microns (0.050 mm). This gauge provides a stable barrier against dust and moisture without adding unnecessary bulk to your packaging.
We manufacture this ldpe packaging using 100% virgin polythene. Because we use raw, non-recycled material, the bags have high clarity and reliable tear resistance. They're sold in packs of 500 pieces per carton.
Recommended Applications
- Industrial parts: Packaging metal fasteners, plastic components, and small hardware kits.
- Apparel and textiles: Packing t-shirts, socks, and other soft goods.
- Documentation: Protecting instruction manuals and printed brochures inside larger shipping boxes.
- Retail organization: Grouping small goods for warehouse storage and quick inventory counts.
Product Limitations
These bags are not certified for direct contact with food or medicines. If you're packaging heavy, sharp-edged metal scrap, a thicker gauge or a specialized heavy-duty rubble sack is a safer choice.
Handling, Sealing, and Air Release
This plastic bag ldpe layout is highly heat sealable. It works reliably with standard impulse hand sealers or automated heat-sealing lines. The high transparency of the virgin material ensures barcodes scan perfectly through the film, so your team won't waste time tape-peeling or manual-keying. For high-speed packing lines, you can order these with an optional 3 mm venting perforation. This tiny air-release hole lets trapped air escape instantly when you compress or stack the bags, preventing shipping boxes from ballooning.
How to Choose the Right Size
If your items are wider than 150 mm but need extra length to fold or tape the top, this 170 x 350 mm size is the logical step up. If you don't need a heavy-duty rubble sack but still require reliable puncture resistance, this 50-micron film is the ideal middle ground. Industrial distributors, e-commerce fulfillment centers, and electronics manufacturers rely on these ldpe plastic bags for daily packing operations.
