The Five Common Materials Used to Manufacture Reusable Grocery Bags

The steady drive for a wide variety of fabrics and materials. Each has its strengths and drawbacks.

The choice often comes down to the unique requirements of the business. Determining the difference between polypropylene, nylon, and reusable polyester bags will ultimately lead to the decision on which one will work for your business brand and your overall business message. Being environmentally friendly attracts discerning customers, so it makes sense to carry the message to the bag you use for promotion.

The following information looks at the more popular materials used for reusable grocery bags.

1. Cotton

Cotton bags can be made from organic cotton (grown without pesticides), recycled cotton (reclaimed cotton scrap), or traditional cotton (chemically treated, raw and natural). Cotton comes in different densities, with denser varieties being heavier. Conventional cotton canvas bags are thicker and costlier than lighter cotton bags.

Advantages of reusable cotton bags include the soft, smooth texture, strength, durability, biodegradability, wide availability, and ease of washing. Its drawbacks are susceptibility to moisture damage, high production and shipping costs, and shrinking from machine washing.

2. Polypropylene

Polypropylene is a versatile resin polymer. Its low production cost and relative durability have seen nonwoven polypropylene as one of the best materials for reusable bags. Plus, polypropylene is measured in grams per square meter (GSM), a gauge of the density and weight of the material. Bags with higher GSM are more substantial and more expensive.

People who prefer woven polypropylene grocery bags usually cite their strength, resistance to chemical corrosion, ease of wiping clean, low porosity, diversity of color options, and flexibility in brand printing. However, its major disadvantages are that it’s non-biodegradable, made from petrochemicals, isn’t soft to the touch, and is unsuitable for machine washing.

3. Nylon

Nylon is a synthetic polymer initially produced as a substitute for silk in fabrics.

Nylon fabric is typically found in track pants, tights, lightweight jackets, pantyhose, swimwear, umbrellas, etc. More recently, it has found application in reusable bags thanks to its ease of maintenance.

Nylon reusable bags are durable, strong, lightweight, readily foldable, easily dyed, and water-resistant. They are, however, non-biodegradable, petroleum-based, and acquire a crumpled, unpleasant appearance under heavy use.

4. Polyester

If you took time to examine the labels on your clothes, one type of fabric is likely to come up more than most: polyester. Polyester is a polyethylene terephthalate (PET) polymer, the same material used to make drink bottles. It was invented in 1941 but gained traction in the 1970s when disco wear was taken by storm. Polyester would, after that, be disparaged as the fabric for cheap suits, but its reputation has steadily improved as quality and application increased.

Polyester reusable bags are versatile, water-resistant, do not crinkle easily, and are foldable. On the flip side, the bags are made from plastic, the material doesn’t break down easily upon disposal, and heavy use leads to wearing off any branding ink on its surface.

5. Hemp

Hemp is not only drought tolerant but also thrives without the need for fertilizers or pesticides. An acre of hemp yields 3 to 6 tons of fiber while needing little water to grow. Hemp fiber is long, strong, and durable. It’s excellent for making organic reusable bags.

Hemp reusable bags are robust (multiple times stronger than cotton), durable, rot-resistant, soft, and smooth to touch. They can be machine washed, ‘break in’ with repeated use (in a similar way to leather), and combined with other materials such as recycled PET or cotton. On the downside, hemp usually has to be imported in much of the Western world, which adds to the overall cost of the bags.

Summing Up

No matter what type of reusable bag you choose or your business provides for customers, it’s always better for the planet than the alternative, i.e. single-use plastic or paper bags. Initially, reusable bags were drab and boring and, as such, not popular. However, reusable grocery bags have become sophisticated and fashionable, so more customers are willing to be seen with them.

When buying a reusable bag, pay attention to the denier number. It’s a measure of the strength of a material. The higher the denier number, the stronger the material.
