PP nonwoven fabric hidden in daily life: shopping bags, takeaway bags, luggage covers all rely on it

2026-06-16

PP non-woven fabric, also known as polypropylene nonwoven fabric , is made from polypropylene particles through melt spinning and hot pressing bonding. It does not require textile weaving, has low cost, is lightweight, durable, waterproof and moisture-proof, and is currently the most widely used non-woven fabric material in civilian and commercial scenarios. It can be seen everywhere in supermarkets, restaurants, travel, and homes.

Common PP non-woven fabric products in daily life

1. Supermarket eco-friendly shopping bag (most typical application)
Most of the reusable white/colored thick shopping bags in supermarkets are made of PP spunbond non-woven fabric.
-Advantages: Strong toughness, far superior load-bearing capacity compared to disposable plastic bags, resistant to pulling and not easily broken; After being coated with waterproof film on the surface, it will not leak water and will not get wet when storing fresh or cold drinks; Can be cleaned repeatedly and used multiple times, meeting the environmental protection requirements of plastic limit regulations.
-Differentiation: Thin disposable dust bags are mostly made of ordinary PP non-woven fabric, while those with glossy film coating are made of laminated PP non-woven fabric, which has a stronger waterproof effect.

2. Delivery insulated bags, catering packaging bags
The inner insulation layer and the main body of the hand-held packaging bag for milk tea, barbecue, and fresh food delivery are all made of PP non-woven fabric.
Ordinary takeaway tote bag: lightweight PP non-woven fabric, low cost, clear printing, can print merchant logo, replacing disposable plastic bags;
Thickened insulation bag: The outer layer is made of PP non-woven fabric that is wear-resistant and dirt proof, and the inner layer is made of composite aluminum foil. With the heat-resistant and moisture resistant properties of PP material, it locks in temperature and is suitable for both hot and cold meal delivery;
Outer layer of fresh ice pack: waterproof laminated PP non-woven fabric, which blocks the penetration of ice water and will not leak and wet the delivery box.

3. Luggage protection cover, luggage dust cover
All luggage jackets commonly used for travel are made of PP non-woven fabric.
-Performance advantages: Lightweight texture, extremely small volume after folding, does not take up luggage space; Anti friction, can protect the box from scratches and bumps during transportation; Waterproof and dustproof, can directly isolate dust and stains during rainy days, airport check-in; Both disposable thin and reusable thick versions are made of PP material.
-Subdivision: Short distance disposable dust covers are made of thin PP non-woven fabric, and repeatedly used thick box covers will increase weight and improve wear resistance.

4. Other PP non woven fabric products that can be seen everywhere
Disposable items: non-woven fabric on the outer layer of masks, disposable bed sheets and pillowcases, shoe covers, protective clothing surface, and face towel base;
Home storage: clothing dust cover, storage bag, outer layer of cotton quilt compression bag, shoe storage bag;
Agriculture/Industry: Seedling bags, fruit tree insect proof cloth, furniture packaging dust-proof cloth, car seat dust-proof covers;
Medical scenario: Disposable surgical placement and isolation clothing substrate, relying on the non-toxic and non bacterial properties of PP.

PP non-woven fabric core characteristics, suitable for various scenarios

1. Lightweight, high-strength, and resistant to pulling and pulling
Polypropylene itself has a low density and is stronger than plastic film and cotton cloth under the same weight. It is not easy to tear when carrying heavy items in shopping bags or suitcases.
2. Waterproof and breathable option
Pure PP non-woven fabric is breathable and permeable; After laminating treatment, it is completely waterproof and can be made into insulation bags and waterproof shopping bags according to needs, flexibly adapting to different uses.
3. Chemical stability, temperature and moisture resistance
At room temperature, it does not corrode or mold, and is not easy to absorb moisture. Hot food in takeaway packages and luggage stored for a long time will not be damaged by moisture; Resistant to low temperatures, it will not become hard or brittle when used outdoors in winter.
4. Environmentally friendly and recyclable
The raw material is polypropylene, which is free from textile printing and dyeing pollution. Most thickened products can be recycled multiple times; After disposal, it can be uniformly recycled and pelletized, which has lower degradation pressure compared to disposable plastic bags, and is also the core reason why supermarkets mainly promote environmentally friendly bags.
5. Easy to print and shape
The surface is flat, the color printed logo and pattern have strong adhesion, and the cost of mass customization for catering and supermarkets is extremely low. It has strong plasticity and can be hot pressed into various styles such as handheld, drawstring, zipper, etc.

Simple distinction: PP non-woven fabric vs other fabrics

1. Distinguishing from textile cotton fabric: PP non-woven fabric has no warp and weft yarn texture, and after tearing, it becomes fine fiber yarn, while cotton fabric has woven patterns;
2. Different from PET non-woven fabric (polyester): PP is lighter, has a soft touch, and is cheaper, often used for daily affordable products; PET has higher strength and is commonly used for high-end filtration and geotextiles;
3. Distinguishing from disposable plastic bags: Plastic bags burn and drip oil droplets, while PP non-woven fabric burns without smoke, clumps and shrinks, with better toughness and will not break easily when pulled.

Small usage tips

1. The laminated PP shopping bag should avoid storing high-temperature and heavy oil food for a long time, as the laminated layer is prone to melting;
2. Non woven luggage covers and storage bags that are exposed to long-term sunlight will accelerate aging, so they should be stored away from light when not in use;
3. Thin disposable PP products have limited strength and are not suitable for long-term reuse. Thickened fabrics can be washed repeatedly dozens of times.

From shopping and ordering takeout, to storage and daily dust prevention, PP non-woven fabric quietly replaces traditional plastic bags and cotton fabrics with its cost-effectiveness and versatility, becoming a necessary material for modern life.

Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
