25kg High Strength PE Particle Bag--Heavy Duty Leakage Prevention, Recycling, Intelligent Packaging System Designed for Safe Storage and Transportation of Industrial Raw Materials

25kg PE particle bags are made of five-layer co-extruded structure (LLDPE/LDPE/reinforced layer/anti-static layer/LLDPE), with thickness of 150-250μm, customizable size (regular 60×100cm), heat sealing strength ≥50N/15mm, and tensile strength of longitudinal ≥35MPa, transverse ≥30MPa (GB/T 1040.3). Built-in diamond-shaped reinforcement and anti-static grid (surface resistance 10^6-10^8Ω), suitable for PE/PP/PET and other plastic particles, chemical powders and other automated filling lines, load-bearing 25kg drop test (1.5m height) breakage rate <0.01%, the number of times of recycling ≥ 5 times, the overall cost of 40% lower than traditional woven bags.

Product Features

Industrial-grade structural design:

Five-layer co-extruded reinforcement: the middle layer is added with nano calcium carbonate (15% content), which improves puncture resistance by 200% (≥80N) and prevents PE particles from piercing the corners. Anti-static treatment: carbon black conductive layer (thickness 3μm) and grounding marking line, static decay time <2 seconds (ESD S20.20 standard).


Intelligent sealing system:

Double-channel heat sealing + cold press reinforcement: gradient design of sealing strength (top ≥ 60N/15mm, bottom ≥ 80N/15mm), suitable for high-speed filling machine (60 packets/minute). Leak-proof triangular folding edge: inner folding angle R≥20mm, particle leakage rate<0.1g/package (ASTM D5276).


Environmental protection and efficiency:

100% recyclable material (single PE structure), APR recyclable certification, instant reuse of trimmings. UV anti-aging agent (UV326 add 0.5%), outdoor storage 30 days tensile strength retention rate > 90%.


Usage Scenarios

Chemical raw materials

Polyethylene particles moisture-proof packaging titanium dioxide anti-static transportation bags


Recycling

Plastic broken debris heavy-duty recycling bags modified engineering plastics special film


Comparative Advantages

Strength revolution: compared with ordinary PE bags, the load-bearing capacity is increased by 3 times under the same thickness, and the breakage claim goes to zero.

Cost optimization: recycled 5 times, single cost as low as 0.8 yuan / strip (traditional woven bags 1.5 yuan / time).

High production efficiency: adapted to 300m/min high-speed film blowing line, supporting online static electricity elimination (<50V).

Full chain compatibility: from -40℃ freezer to 60℃ cabin, dimensional stability ±0.5%.


Benefits

Chemical industry:

Anti-static design zeroes out the risk of dust explosion and reduces insurance costs by 30%. RFID traceability system reduces mixing accidents and saves more than 2 million RMB in annual quality costs.


Logistics and Warehousing:

Stacking height is raised to 8 layers (5 layers for traditional bags), storage space utilization rate +60%. Moisture-proof performance (moisture permeability ≤5g/m²-24h) makes the raw material moisture content exceeding the standard rate decreased by 95%.


End users:

Easy-tear notch design (pre-cut V-notch, opening force ≤10N), feeding efficiency increased by 50%. Transparent window (localized high-transparency film) realizes quick inspection and reduces unloading disputes by 90%.


Environmental value:

10,000-ton application to replace woven bags, reducing plastic waste by 15,000 tons and carbon footprint of recycled materials by 70%.
