What is an eco-friendly bag?
Is it a bag that is 100% eco-friendly and does not pollute the environment in any way? Actually it doesn’t exist.
We all know that what can really be 100% environmentally friendly is not to use, not to emit, but this again seems to be impossible. After all, bags are widely used in everyday life, in packaging industry. So we can only use relatively eco friendly bags as far as possible, and to reduce the pollution of the environment as best as we can. So that means, Eco-friendly bags are bags that made from a variety of environmentally friendly materials such as cotton, hemp, non-woven, RPET, biodegradable bioplastics, recyclable paper, they are relatively earth friendly and have less polluting emissions.
So what are the differences between these eco bags that made from different materials? And what areas should they be used in? This article will take you to an in-depth analysis of the similarities and differences of different materials environmental bags, advantages and disadvantages and the application of the industry.
Cotton Bags or Canvas Bags
Broadly speaking,Cotton bags are divided into cotton and canvas, the difference between 100% cotton bags and canvas bags is mainly on the thickness, the main advantage of 100% cotton bags is that they can be naturally degraded, the bags are strong, durable and long-lasting. They are friendly to customize any shapes of bags. For example, tote bags, drawstring bags, travel bags, beach bags, sling bags, handbag, zipper bags. etc., Furthermore, they are good to print and dye. You can see the cotton bag almost everywhere in our daily life. They are also easy to DIY on your own. You can buy almost all price ranges for cotton bag, for small drawstring cotton bags, they are usually very cheap, and for big thick canvas bags, they are expensive than the non-woven bags. But its durability and solidity is much higher than the non-woven bags. 100% cotton made bags are Green products, popular among our customers.
But canvas can also be made of polyester and cotton, like this canvas bag made of polyester and cotton is not as environmentally friendly as cotton, because the bag contains polyester, which is a kind of plastic.
Eco Jute Bags and Burlap Bags
Jute bags are available in two materials: hemp jute and burlap. Usually hemp jute is a sack made of cloth woven from hemp yarn, which is a purely natural and green product. They are more friendly to shape, printing, sewing and other customizations, They are breathable, flexible, light, non-flammable, easily decomposed, non-toxic and non-irritating, recyclable and so on. Burlap, on the other hand, is more natural, with a rough surface that requires specific sewing machines, less vivid and realistic in printing, and the printing color falls off easily, but they are quite firm and purely natural.
Non-Woven Eco Bag(NWPP)
Non-woven fabric is composed of directional or random fibres and is a new generation of environmentally friendly materials.
The main ingredient of non-woven eco friendly bags is PP (polypropylene), the fabric has a variety of colors for customers to choose from,also bag size, thickness, style can be specified by the customer. Non-woven bags are recyclable and reusable products, with a greater chance of use than plastic bags, which are actually not biodegradable and decomposable .
However, non-woven bags are produced in rich, bright and fashionable colours, with a wide range of styles, environmental protection uses, beautiful and generous, varied patterns and styles, and are light and environmentally friendly, easy to carry, inexpensive, with a longer life than paper bags, non-woven bags can be recycled and are internationally recognized as environmental products that protect the ecology of the planet.
RPET Eco Bags
Rpet is a new type of environmentally friendly recycled fabric, which is a textile made from the recycling of discarded cola bottles and plastic bottles. Its recycled material can be regenerated into PET fibers, reducing the pollution of waste, and is very popular in developed countries. RPET sand line manufacturing process is as follows.
PET bottle recycling → PET bottle quality inspection and separation → PET bottle slicing → extraction, cooling collection → Recycle Fabric yarn → weaving into fabric
Therefore, the cost of recycling is also higher: one tonne of recycled PET yarn = one tonne of fabric.
One ton of reused PET yarn = 67,000 plastic bottles = 4.2 tons of CO2 reduction = 0.0364 tons of oil savings = 6.2 tons of water savings.
Recycled plastic bottles made of RPET laminate have been used in large quantities in recent years as material for environmentally friendly shopping bags. The weight of the fabric used for lamination is generally 65-130g, and the weight of the fabric used for printing is generally 130g-300g, which can be screen printed or heat transferred to make finished bags. It can be used for shopping bags, advertising bags, ice bags, insulation bags, gift bags, etc. The thickness and weight of the material can be adjusted according to the different needs of customers.
Bioplastic disposable bags（PBAT+PLA）
PBAT+ PLA bags are usually used in disposable packaging industry. They are 100% fully degradable and can be printed with text, making them a good alternative to PET bags, but they are relatively expensive.
PBAT+ PLA bags are usually made from fully degradable materials that is certified by OK compost..
Paper bags can usually be divided into ordinary disposable paper bags, washable paper bags and DuPont paper bags.
Ordinary material paper bags, which are usually just used in the disposable packaging industry, can be divided into food grade and non-food grade. Reusable paper bags are currently popular with washable paper bags and DuPont bags, which are more costly, but beautiful, strong and popular with the public.
