Core Characteristics |
Applicable Scenarios |
Purchasing Tips |
|
Polyethylene (PE)
|
HDPE (High Density) |
High hardness, tensile resistance, low cost; poor puncture resistance, easy to become brittle when holding wet garbage |
Household dry waste, economical vest bags, office paper scraps |
Choose new materials instead of recycled materials; thickness ≥ 0.012mm for better durability |
|
LDPE (Low Density) |
Soft, transparent, good stretchability; medium load-bearing capacity |
Office light waste, thin flat bags, fresh-keeping liners |
Suitable for light loads, not recommended for heavy objects |
|
|
LLDPE (Linear Low Density) |
Strong toughness, puncture & tear resistance; best overall performance |
Kitchen wet waste, garbage with bones/sharp objects, thickened styles |
First choice for household use, higher cost performance when blended with HDPE |
|
|
Biodegradable Materials
|
PLA + PBAT Composite |
Biodegradable (compliant with GB/T 38082, EN 13432), eco-friendly |
Kitchen waste, outdoor composting, environmental protection scenarios |
Degrades under industrial composting conditions, slow degradation at room temperature |
|
Starch-based |
Fully compostable, plant-based raw materials |
Organic waste, high-end environmental needs |
High cost, easy to soften in humid environments |
|
|
Special Functional Materials
|
PP (Polypropylene) |
Heat resistance, chemical corrosion resistance, high hardness |
High-temperature waste, industrial chemical-containing waste |
Not resistant to low temperature, easy to brittle at low temperatures |
|
Metallocene PE |
Excellent puncture & tear resistance, stronger load-bearing |
Heavy-duty waste, decoration waste, sanitation collection |
Higher price than ordinary PE, suitable for heavy loads |
|
|
Puncture resistant Composite |
Added fiber/coating layer, anti-sharp objects |
Glass fragments, fish bones, metal scraps |
Ideal for heavy kitchen waste to prevent breakage and leakage |
