How to Choose Non-Woven Bags: The Complete Guide to Thickness, Durability and Branding

To choose the right non-woven bags, focus on three parameters: fabric thickness (measured in grams per square meter, GSM, where 70 to 80 GSM suits shopping and 100+ GSM suits heavy use), handle type (heat-sealed, or stitched for maximum strength), and printing method (flexo for simple designs, or lamination for complex designs and water resistance).

What exactly is non-woven fabric, and why has it taken over the market?

Non-woven fabric, or Non-Woven Polypropylene, is a revolutionary material that isn't made in the traditional way of weaving threads (warp and weft), but by bonding synthetic fibers together through mechanical, chemical or thermal processes. The result is a fabric that is lightweight, flexible, very strong and relatively cheap to produce. In many countries, non-woven bags have become an inseparable part of shopping and marketing, especially since laws restricting single-use plastic bags made them unwanted and uneconomical.

Beyond the legal aspect, non-woven bags offer a huge marketing and environmental advantage. They're reusable, recyclable, and offer a wide, prominent advertising surface that moves around the streets for months and even years. Whether you're a business owner looking for a branded packaging solution or a consumer who wants to get organized at home or when shopping, understanding the different types of non-woven bags will save you money and spare you the frustration of bags that tear at the worst moment.

The deciding parameters when choosing a non-woven bag

When you set out to choose or order non-woven bags, there are three technical characteristics that will determine the quality of the bag, its durability and its price:

1. Fabric thickness and weight (GSM)

This is the most important measure of a bag's durability. GSM stands for Grams per Square Meter. The higher the number, the thicker, stronger and more premium the bag:

• 40 to 50 GSM: very thin bags, usually single-use or meant for especially light products such as swimwear or light cosmetics.
• 70 to 80 GSM: the standard for retail chains and supermarkets. Bags strong enough to carry weekly groceries, durable for many uses.
• 100 to 120 GSM: extra-thick premium bags. Suitable for carrying bottles, heavy catalogs, electronics, or for long-term reuse as an everyday tote.

2. Handle type and attachment method

The handle is the weak point of any bag. There are two main methods of attaching the handle to the body of the bag:

• Heat sealing (Heat-Sealed): attachment using heat, without thread. This method is faster and cheaper, and suits bags meant for light to medium loads.
• Stitching (Stitched): classic stitching with thread, often with an X-shaped reinforcement (X-stitch) at the base of the handle. This is the recommended method for heavy bags, since it keeps the handle from tearing off under load.

Printing and branding methods for non-woven bags

If you're choosing bags for your business, branding is critical. The way your logo is printed on the bag will affect not only the look, but also how long the branding lasts:

• Screen printing (Silk Screen Printing): the most common method for small and medium runs. Suitable for simple designs with a limited number of colors (no gradients). The print is fairly durable but may wear over the years.
• Flexographic printing: suitable for huge orders (tens of thousands of units). Very fast and cheap per unit, but requires expensive printing plates and is limited in how precisely it reproduces small details.
• Lamination (BOPP): the most advanced method. The design is printed in full process color (like a color photo) on a thin layer of plastic, and the non-woven fabric is then coated with that layer. The result is a glossy or matte bag, completely waterproof, rigid and easy to clean, with a print that never fades.

Non-woven bags vs other packing and organizing solutions

When it comes to smart packing, whether for carrying everyday groceries or organizing your personal gear for travel, the material the bag is made of determines the quality of the experience. While non-woven bags are an excellent, cheap and accessible solution for mass distribution and supermarket shopping, we often need more durable and sophisticated solutions for organizing our personal gear.

For example, in the world of travel and trips, materials like canvas, ballistic nylon or durable polyester replace non-woven fabric to give gear maximum protection. Using dedicated packing organizers made of light, durable materials lets you divide your suitcase or backpack smartly, much like non-woven bags divide our groceries, but with durability for many years and convenient zippered compartments.
