The ultimate goal of this "Multi-function Cotton Gauze Grocery Bag" is to replace all together the Plastic shopping bags, Heavyweight Tote Reusable bags and Paper bags

Part A-Design

The present invention offers the most cost-saving, effective alternative of Handle design for the grocery bag that will reduce up to 30 % waste of Textile, Fuel, Manpower and Energy Vs traditional grocery bags in the Market

There are two traditional bag handle designs most often available in the market. "Attached" and Cutout Holes* handle designs applied to any kind of woven and non-woven fabrics.

A new design (without attached handles) features Handles incorporated into the body of the bag with fabric INTACT - one square piece 45 x 45 cm.
Handles are created by leaving a gap during the sewing process (break on sewing ) of around 16 cm on both sides of the bag .The 16 cm gap acts as handle and allow the user to carry the grocery bag with a firm grip.

This unique handle design uses up to 30% less fabric and fuel for its transportation, and up to 9 times less Manpower and Energy Vs traditional grocery bags in the Market.

Furthermore using Self-finished edges of the textile (so called Selvage) at the opening of the bag on this new design will reduce also the cost of sewing process on the bag's opening that will results less Manpower and Energy

For *Detailed Competitive Analyses* of this new handle design VS traditional ones in the Market see the link below.

Due to its simplicity the new design will allow the bag to be produced in large scale (mass-produce) and easily fit onto existing (adapted) traditional plastic grocery bag hooks allowing a quick and cost-effective transition in supermarkets from “a single-use plastic bag” to “cotton gauze eco-friendly bag.

It is highly beneficial to make Textile Industry ( particularly bag manufacturers) and Retail stores aware of this new design which is clearly very sustainable and economical. They should also consider that shoulder handles such as "Attached and Cutout hole" :are not necessary, especially for grocery bags which will be used from Store-to Cart-to Car- to Home.

The most important point is that this sustainable solution does not need any additional investments in infrastructure or machinery to be implemented.

The only support needed for this product is to bring it in Market Level. The grocery Bag Manufacturer simply have to consider replacing the use of traditional "Attached or Cutout Hole:" designs (appled to any kind of fabric), with this new design, in the same location with the same machinery.

Living on our time when the global warming crisis is one of the biggest concerns our planet is facing, a new and improved handle design of any kind of fabric (rayon, synthetic or cotton) can do it's part helping our planet from extra fabric used for handles, save fuel for transportation and above all, save energy and manpower for services that can be eliminated.. This kind of bag handle is designed to be applied not only to grocery bags, but to any kind of fabric used by the logo bags in cloth stores or Home Depots etc.

Part B- The never-ending life cycle of cotton gauze grocery bag.

Design (part A) is the first step of this invention in support of sustainability that can be applied to any kind of fabrics rayon, synthetic, polyester or cotton.

However this invention offers also another alternative:

A combination of this simple design with the lightest and most absorbent possible cheesecloth gauze fabric will make the grocery bag " multi-function" that later can easily unfasten to be used as replacement of many cotton Items at home such as:

-Washable cotton Diapers Inserts/pads.
-Burping/Spit-up Cloth for baby
-Replace Dishcloth and cleaning cloth used for general cleaning
-Use as cotton napkins in kitchen to replace paper towels.
- Use it as a dry trash bag.
-A final incredible use for the gauze bag in the house is easily to be used as replacement of "Reusable microfiber/cotton Mops" (with or without gripper handles )
-also be washed, and reused for all of the above, including as a reusable grocery bag if needed:

Invention was created with this question in mind:

"""How to combine the lightest and most absorbent possible cotton material with a unique grocery bag design that after bringing our grocery at home can replace all of above""".

A combination of gauze cheesecloth (preferably grades #50 -70) fabric with this new handle bag design can produce "The never-ending Life cycle of a cotton gauze grocery bag"

For more information about the life cycle product please see the publication of this invention to the European Circular Economy Stakeholder Platform

The ultimate goal of my invention is to replace all the grocery bags presently in the market. (single-use plastic bags, paper and heavyweight reusable cotton bags), since each of them has their own problems.

A- Plastic shopping bags that are the only mass produced single use grocery bags in the market are now an omnipresent global product due to having a devastating impact on human health and our environment.

B- Heavyweight Tote, canvas) Reusable shopping bags that are brought in the market to replace plastic bags have even more problems:

- They are thicker, heavier, and not very comfortable to be washed every time after been used, bringing a hygiene issues that arise by which can become dirty with time thus heightening the danger of spreading food-borne illness.
Reference:

In this age of food related epidemics, customers and food purveyors will be ever more mindful of cross-contamination.
The present invention can help reduce the hygiene issues and solve those concerns

-Tote/canvas reusable bags” being thicker and heavier they have lower water absorption properties plus their design with attached handles not allowing them to be multi-function.

The present invention offers a multi-function product that will saves the customer money in the long run, and additionally will be in support of sustainability

C- Paper bags relies on cutting trees that requires years to grow up
- They are prone to wetness. This condition does not affect the gauze bag
- The Gauze bag can also be used as a cleaning cloth, which also reduces the usage of paper towels at home.
- Paper bags are heavier and require more fuel for their transportation.

I have based some of the following comparison points on information obtained in the following website:

Link

(Note: Nashville Wraps sells both paper and plastic bags)
According to this article the weight of 1000 paper bags is around 140 lbs.
The weight of 1000 gauze bags (grade #60) is around 37 lbs.
This weight difference will affect the transportation costs: around 3.7 time more gas for each full truck load will be need for paper bags Vs gauze bags

Here there are some more facts/advantages:

i) Regarding achievement of this product to be a multi-function is due to the material chosen for this project.
According to Textile industry Cotton Gauze Cheesecloth fabric is available in at least seven different grades, from open to extra-fine weave that are distinguished by the number of threads per inch in each direction. The grades can be #10, #40, #50, #60, #80 and #90.
The lower the grade of Gauze fabric used for the grocery bag, the less cotton will be required and the smaller footprint it will have on the environment.

Considering that the bag is going to be used for a short time (of about 12 minutes from market to the house), the medium grades (grade #50- #70) will satisfy both the customers’ needs and the environment. Such bags will weighs only 0.5-0.7 oz./bag ( 14 gr-20 gr/bag) and can carry up to 15 pounds groceries.

ii) Gauze cheesecloth fabric is manufactured by Textile Industry mainly (but not limited) under the following names:

- 100% cotton absorbent Medical (bleached and sterilized) gauze, used for Medical purposes to cover or wrap and allow wounds to “breathe” while absorbing fluids.

- 100% Kitchen Cotton Cheesecloth (bleached or unbleached) to be used for **ALL-PURPOSE CLEANING"* such as dish or any other type of household surface cleaning, car cleaning, etc.

The most important point of this project is offering the Bag Manufacturers the credit to turn this 100% Kitchen cotton cheesecloth with very simple design to a grocery bag, ship it to a Retail store and let customers use it as an **all-purpose cleaning cloth** upon bring the groceries home.

iii) Used as a Diaper inserts the cotton gauze is more absorbent than the microfiber or bamboo versions commonly sold in the market. Cotton retains moisture under pressure better than microfiber or bamboo (the same applies for all other cotton items that gauze bag will replace at home).

iv) Since the gauze fabric is thin and light, the bag requires very little storage space, making it convenient to be machine washed and saved on the kitchen drawer for use as a cleaning cloth, diaper inserts etc. when needed

v) Regarding the hygiene issues arise from Tote /canvas Reusable bags mention above the problem is solved by presenting a design “that instead bringing cotton Reusable bag 150 times back into food selling establishments (,as required for the heavy tote/canvas bags) offers a bag that can be used and reused at home as a replacement of many cotton Items that customers normally buy separately in the market. (Customers also have options to reuse it 4-5 times as reusable bags, if needed)

vi) The new grocery bag design in shape of one square piece with no attached handles makes it easily unfasten to turn the bag to a cleaning cloth. Diaper Inserts, cotton napkins etc.

vii) Furthermore, function as a cleaning cloth will replaces some of the uses of the traditional paper-towels saving the user money and reduces reliance on trees for paper products.

viii) . Sanitary advantages:

Cleaning sponges and non-woven dishcloths available in today's market do not allow air to pass through easily thus become breeding ground for dangerous food-borne bacteria. The tiny air holes in the lower grade gauze fabric not only give it higher water-absorption properties, but also allow it to quickly air dry.

This unique aspect of the gauze fabric makes it extremely sanitary and especially valuable for use in the kitchen where food is handled and the spread of disease carrying bacteria is more commonly found

***MY VISION My is to eliminate the use of single-use plastic bag.

In fact, there is no need for grocery bags to be either:
- Plastic (that has a devastating impact on human health and our environment.
- Paper (which relies on cutting trees that requires years to grow up) or
- Heavyweight cotton Tote bags (which are thicker, heavier, and not very comfortable to be washed every time after been used, bringing hygiene issues).

Instead my vision is for the Global Grocery Bag Industry to shift by using compostable, lightweight cotton fabric, with highest water absorbent capacity, (such as Cheesecloth), so the grocery bag can be a Multipurpose Product able to replace at home many washable cotton items with a never ending life cycle


Financial information

**Cotton production worldwide is around 25 million ton/year.

In order to replace 400 billion plastic bags worldwide, around 7 million tons of cotton/ year (out of 25 tons) will be needed to replace all of them with cotton gauze bag

(Note: Cheesecloth Grade #60 weighs 17 gr cotton/bag. Gauze fabric as raw material cost $0.07/bag)


This solution will help to lower cotton yearly production: If this gauze bag is washed and reused at least four times as reusable bag (besides being used at home as replacement of other cotton items), the cotton amount will be reduced down from 7 to 2 million ton /year

What is more, with this amount not only we will replace all plastic bags, but at the same time will drastically reduce cotton production for other washable cotton items such as Diapers Inserts, Burping/Spit-up baby cloth, Kitchen cotton napkins etc. which are already Manufactured by Textile industry and sold separately in the market

**Gauze Cheesecloth fabric is available in at least seven different grades, . The grades can be #10, #40, #50, #60, #80 and #90.

Cheesecloth Grade # 10 - #40
Weight: 0.3 oz -0.4 oz cotton/bag and can be used to carry light items (up to 8 pounds)

Cheesecloth Grade # 50 -#70
Weight: 0.5-0.7 oz. cotton/bag and can be used to carry up to 15 pounds groceries.

Cheesecloth Grade #80-#90
Weight: 0.8-0.9 oz. cotton/bag and can be used to carry heavy items on Home depot over 15 pounds

NOTE: Due to a simple design, sewing time for this new grocery bag is 10-15 seconds
