In today’s competitive market, businesses are moving away from single-use plastic bags toward eco-friendly, reusable solutions.
Among them, the PP non woven bag has become a favorite choice for retail stores, supermarkets, trade shows, and promotional events.
However, not all non woven bags are made equal.
If you’re sourcing from overseas suppliers, understanding what makes a high-quality PP non woven bag is essential — it ensures your bags are durable, presentable, and worthy of your brand.
Let’s break down the key factors that define quality in PP non woven bags.
1. What Is a PP Non Woven Bag?
PP (Polypropylene) non woven bag is made from spun-bond non woven fabric, produced by bonding polypropylene fibers together through heat and pressure instead of weaving or knitting.
This process makes the fabric:
-
Lightweight but strong
-
Breathable
-
Recyclable and reusable
-
Customizable for different designs and printings
These features make PP bags a cost-effective and sustainable packaging alternative widely used across industries.
2. GSM – The Foundation of Bag Quality
One of the most important indicators of quality is GSM (grams per square meter) – it measures the fabric’s thickness and weight.
-
Low GSM (60-80): suitable for lightweight products, giveaways, or short-term promotions.
-
Medium GSM (90-110): ideal for shopping bags, grocery bags, or event bags.
-
High GSM (120+): perfect for heavy-duty applications, carrying bulky or heavier items.
✅ Tip: A high-quality PP non woven bag typically has a consistent GSM across the entire surface – no thin or weak spots.
3. Strong Stitching and Reinforced Handles
The durability of a non woven bag largely depends on how it’s stitched.
High-quality bags have:
-
Tight and even seams (no loose threads)
-
Cross-stitched handles for better strength
-
Double-folded edges to prevent tearing
If a bag’s stitching looks messy or uneven, it’s a clear sign of poor workmanship – and the bag might fail under minimal load.
4. Lamination: Strength + Style
There are two main types of PP non woven bags:
-
Unlaminated bags: Matte texture, more breathable, suitable for simple printing.
-
Laminated bags: Glossy or matte lamination layer that enhances water resistance, durability, and vibrant printing.
High-quality laminated PP non woven bags not only look premium but also withstand moisture and repeated use.
They’re ideal for brands that care about presentation and longevity.
5. Print Quality and Brand Visibility
For businesses, a bag isn’t just packaging – it’s a moving advertisement.
That’s why printing quality is a key factor in assessing overall bag value.
Look for:
-
Sharp and consistent logo printing
-
No color bleeding or smudging
-
Long-lasting print even after multiple uses
At Hanpak, we use flexo, screen, and gravure printing technologies, ensuring every custom PP non woven bag reflects your brand identity perfectly.
6. Eco-Friendliness and Reusability
A high-quality PP non woven bag is built to be reused many times.
The more durable it is, the longer it stays in circulation — reducing plastic waste and supporting your company’s sustainability goals.
Unlike disposable plastic bags, non woven bags:
-
Can be reused over 100 times
-
Are recyclable
-
Require less energy to produce
-
Support “go green” initiatives
This makes them the ideal eco-friendly choice for companies promoting sustainable branding.
