Let’s consider a popular material for bags
Polyester
The most popular and affordable material for making any type of bag. This synthetic fabric is characterized by its lightness and at the same time high strength. Polyester perfectly tolerates both severe frost and sun exposure. It does not deform during wear.
Polyester can be impregnated with special compounds to repel moisture. As for care, bags can be machine washed or hand washed. They retain their shape perfectly and dry quickly.
Suede
The main feature is the soft short pile on the inside and on the front side of the fabric. Suede is made of cotton and silk. It has an attractive appearance, wear resistance, and is also pleasant to the touch.
Usually, women’s bags are sewn from suede. The material looks aesthetically pleasing and, as a rule, does not need additional decoration.
Nylon
Nylon is used to make a huge number of types of clothing – underwear, stockings, jackets, covers and, of course, bags, mainly tourist and sports. Features:
- high wear resistance;
- strength;
- lightness;
- variety of colors;
- moisture resistance;
- resistance to sunlight;
- affordable price.
A nylon bag is a durable and reliable product that will show itself only from the best side in any conditions.
Oxford
Synthetic fabric made from nylon and polyester. To protect against wind and moisture, oxford is coated with colorless polyurethane. Thanks to nylon, the fabric does not wear out and does not react to the effects of chemicals. This is an ideal material for tourist backpacks. Oxford is durable and elastic, as well as moisture resistant.
It is important to consider that oxford deforms when strongly heated, so products should be stored away from heating devices and fires.
Eco leather
This is an artificial substitute for genuine leather. As a rule, it consists of two layers – a woven textile fabric and a polymer top layer. The material is dyed, and also given a texture that is indistinguishable from natural leather. Cotton and polyester are used for the base.
Main characteristics:
- easy care;
- hypoallergenic;
- breathability;
- strength;
- elasticity;
- dimensional stability;
- resistance to dirt and water;
- does not harden in the cold.
To remove dirt from eco leather, as a rule, it is enough to wipe the product with a soap solution and wipe dry.
Genuine leather
Genuine leather is considered a standard material for the manufacture of various accessories, including backpacks. The main advantage of leather is its wear resistance. With proper and high-quality care, the product can last for decades without losing its original appearance and shape. If desired, the backpack can be repainted or restored if the material is worn out. Leather bags are pleasant to the touch, but it is important to consider that leather can become stiff in the cold.
Usually this material is used for sewing city or business bags. Leather is usually not used for tourist models.
Materials of manufacture and features of choosing shopping carts
A typical shopping cart is a folding metal frame on two wheels, which usually comes with a bag. When choosing models that make it easier to carry food, clothes and other things, it is customary to be guided by four criteria.
First, pay attention to compactness. A shopping cart must fold. The first option is the ability to adjust the length of the metal frame and fold the lower platform, the second – when, in addition, you can change the position of the wheels (set them in the same plane). In the second case, the product, as a rule, can be placed in a niche 10 cm wide.
Second, they look at durability. A structure assembled from short-lived materials will quickly become unusable. This usually happens on the road, which is doubly offensive.
Third, lightness is important. If the cart is heavy, then you will have to make extra efforts during the transportation of luggage.
And lastly, the price of the product. This aspect is relevant when choosing any product.
What are shopping carts made of
The optimal frame is a structure made of small-diameter steel pipes. An alternative option is aluminum, but this lightweight metal is less durable. Manufacturers usually make wheels from cast rubber, since with a small diameter there is no point in using inflatable ones. They should be wide and reliable enough, since they sometimes carry a load of 50-60 kg.
You should also pay attention to the material of the cart bag. In the classic version, practical rubberized fabric is used. It should be strong enough so that holes do not appear from possible friction against the frame during transportation. The bag can always be removed and washed.
Nuances of choosing a shopping cart
- It is advisable to choose a product in a specialized store that can offer a wide range.
- Think about what weight and size of luggage you will most often have to deal with.
- Decide on the price category and ask to show a model that is made of reliable materials and looks nice.
- Do not rush to pay for the first option offered. Check how well the folding technology of the shopping cart is thought out, how conveniently it rolls.
- It is worth paying attention to the presence of a leg for fixing in a vertical position. There are models on triple wheels for moving along flights of stairs, some even have a folding seat.
- And the last point is the handle of the cart. It should not be too thin, otherwise it will cut into the wrist
Customer requirements for a shopping cart
-At the request of customers, the approximate price of the product should differ from $ 40 to $ 60
-Strength decreases with age, and a decrease in strength can jeopardize the functioning of the body. For example, almost half of women over 65 and more than half of women over 75 cannot lift 4.5 kg. The same applies to older men. At this age, it is better not to lift heavy things.
Therefore, the cart must be able to withstand the weight of a grocery basket for a large family. -Material requirements. The cart should be made of high-quality materials, but at the same time fall within the price range ($40-60). Customers also said they wanted recyclable materials. -The cart can be either electric or regular. -Additional functions of the cart. Have a brake so that you can control the speed when going down the hill. The cart should have a function such as a seat. Usually, when older people go shopping, it takes a lot of time and they walk a lot. Not all markets have the opportunity to find a bench, so the cart should have a seat. Additional hooks for a bag, umbrella. The ability to put a glass or a bottle of water. The ability to measure the weight of the goods yourself, as well as flashlights for dark markets.

The handle folds and is height-adjustable; -there is a screen on the handle that displays such functions of the bag as: weight measurement, bag lock mode, wheel lock mode, turning on the flashlights, switching to manual mode (since the bag is electric, it needs to be charged, but there are times when they forget to do this.

I would like to add an old Russian pattern. Since the customers wrote that the design should be simple, not in bright colors. In order not to make the bag monochromatic, I think adding a small pattern will look interesting.
If the customer does not like Russian pattern, it can be replaced with a classic Chinese one.
