Key Advantages
1.High load capacity & long service life
Far stronger and tear-resistant than non-woven fabrics of the same weight. Load range spans 2.5kg to 200kg. Qualified woven PP bags can be reused over 100 times without easy deformation or rupture even with heavy groceries.
2.Lightweight & moisture-resistant
Low material density enables easy folding and carrying. Raw PP barely absorbs water. Laminated versions deliver full waterproof performance for rainy-day use.
3.Easy to clean & food-safe
Surface stains can be wiped off simply with a damp cloth. Polypropylene is odorless, non-toxic and safe for food packaging.
4.Cost-effective & recyclable
Lower production cost than natural fiber bags such as cotton and jute. Woven PP bags can be recycled after service life.
5.Excellent printability
Compatible with standard printing and laminated full-color printing. Bright graphics and custom logos make them ideal for brand marketing.
Limitations
Virgin PP lacks UV resistance; prolonged outdoor exposure leads to brittleness. This can be improved by adding UV stabilizers.
Impact resistance drops under low temperatures, making bags prone to cracking in frigid conditions.
The material is flammable and should be kept away from open flames and high heat sources.
Fabrics over 150gsm are stiff and hard to fold. For consumer shopping bags, 80–100gsm is recommended to balance portability and strength.
