8 tips for choosing debris bags

8 min


Any renovation begins with the preparation of the premises. Old wallpaper is removed, the plaster is knocked off, tiles are chipping off, partitions break – there is a lot of garbage, it is heavy and sometimes with sharp edges. You can’t put it in a simple garbage bag – it will instantly break. A way out of the situation has long been invented – special bags for construction waste. True, few people think about the nuances of choice when buying them. As a rule, almost the first available bags are purchased, and it is not the indicators of strength, volume and thickness that come to the fore, but the price. This approach is fraught with unpleasant consequences: the bag may burst at the most inopportune moment, and the cleaning and transportation of waste will be delayed. Let’s save your nerves, money and time and learn how to choose the right bags for construction waste.

# 1. What are construction waste bags made of?

For home and office, the simplest plastic bags with a volume of 30-60 liters are usually used. They can easily withstand several kilograms of household waste, but such a container will not withstand pieces of old plaster or tiles. Such bags have low strength and load capacity.

A good bag for construction waste should be roomy, durable, resistant to mechanical damage, easy to fill and carry. It is important that the price is not too high.

For the removal of construction waste, bags are used made of:

  • polyethylene;
  • polypropylene.

The properties of each type are highly dependent on production conditions.

Plastic garbage bags

Depending on the production conditions, plastic bags are of several types:

  • bags made of high density polyethylene (LDPE). Received by polymerization of ethylene at a temperature of + 100 … + 3000C and a pressure of up to 300 MPa. As a result, a soft elastic material with a density of 0.92-0.94 g / cm3 is obtained. LDPE bags are characterized by elasticity, flexibility, health safety and good durability, which remains even at low temperatures. Such bags do not rustle, have a glossy surface, are waterproof, and perfectly resist punctures and cuts. If it is necessary to transport garbage with sharp corners, it makes sense to take just such bags, even though they are inferior in strength to their counterparts made of low-pressure polyethylene;

  • Low-density polyethylene (HDPE) bags are made from more rigid granules, dyes and stabilizers can be added to the raw materials. There are several production methods, most often polymerization in a gas sphere or solution is used, a lower pressure is maintained than in the case of LDPE. The density of the resulting product is 0.93-0.97 g / cm3, it is distinguished by high strength, minimal elongation, moisture resistance and safety. At low temperatures, the size of the bag changes. In addition, HDPE is more fragile than LDPE, i.e. sharp debris can tear the material. You can recognize such packages by the matte surface and characteristic rustling;

  • Medium Density Polyethylene (PSD) is rarely used for the production of garbage bags. This is a composition of LDPE and HDPE with stabilizers and other additives. The content of HDPE and LDPE depends on what properties must be given to the product. For example, to make a LDPE bag more durable, 10-15% HDPE is added to the composition. If the HDPE bag needs to be made more elastic, then up to 15% LDPE is introduced into the mass.

Plastic garbage bags are in great demand due to their excellent performance, low price and huge selection. Products are produced in various sizes, volumes and thicknesses. On the page https://olgapak.ru/products/waste-bags/ presented a decent range of bags for construction waste from the company “Olga and K”, which has been producing plastic bags for 20 years. In the manufacture, modern technologies and high-quality raw materials are used, products are sold in bulk, but it is possible to produce a small batch – from 5000 bags. If you plan to renovate an office or commercial building, then this is a great option – you can do without intermediaries and save money. The offer may be of interest to construction companies as well.

How much debris is generated during repairs? On average, about 10 kg, or 0.2 m3 per 1 m2, i.e. with a room area of ​​100 m2, the waste will be 1000 kg.

Polypropylene bags

More durable bags are made from polypropylene, which can be used several times. This material is also used in the production of bags for storing cereals, so they should be clearly familiar to everyone. The quality of the bags depends on the type of polypropylene and the density of the weave.

The general principle for the production of this type of bags is as follows. A film is obtained from polypropylene granules, it is cut into thin strips from which the fabric is woven. The result is a durable sleeve without seams. The sleeve is cut into blanks, from which the result is bags that can withstand from 5 to 65 kg.

The following types of polypropylene are used for the manufacture of bags:

  • primary. It is more durable, has a white color, and is used for storing food products: sugar, cereals, flour, starch. Such bags are not used for garbage disposal, since they are more expensive than those made of recycled polypropylene;

  • secondary. Bags can be made entirely from recycled polypropylene, such products are green, withstand up to 50 kg, and are the cheapest. A portion of the virgin polypropylene may be added to the recycled PP stock. Such bags are gray and more durable, can withstand up to 65 kg, and are slightly more expensive than green ones.

Polypropylene bags are used when you need to immediately take out a large volume of overall garbage. Among their advantages:

  • high strength, resistance to stretching and sharp debris;
  • sufficient roominess;
  • the ability to reuse. With the help of several such bags, you can successively drag a sufficient amount of garbage, while the performance of the products is maintained for a relatively long time;
  • are not afraid of sunlight, low and high temperatures;
  • not subject to putrefactive processes;
  • versatile and safe. Such bags can be used not only for garbage disposal, but also for storing fertilizers, transporting clothes.

The only drawback is that polypropylene bags are more expensive than polyethylene ones. If one polyethylene bag can be bought for 1-8 rubles (depending on the parameters, there are products for 14 rubles), then one polypropylene bag will cost from 7 to 78 rubles.

# 2. Bag volume

The volume of garbage bags ranges from 20 to 200 liters or more. To collect household waste, as a rule, bags with a volume of 30-60 liters are used. In hotels and office centers, large bags of 90 liters can also be used, but their strength is low, because the waste is not very heavy. Bags with a volume of up to 120 liters are used when cleaning yards and streets, in restaurants and canteens, during mass festivities

To collect construction waste, bags with a volume of more than 80 liters are usually used. Bags with a capacity of 240 liters and even 360 liters are available to allow you to take out the waste as quickly as possible.

Remember, too, that the best is the enemy of the good. Do not think that in all cases a large bag is better than a smaller one. If you are dealing with heavy waste, it is better to use bags with a volume of no more than 60 liters, otherwise it will be difficult to remove the collected waste from the site later.

Consider also the parameters of the resulting debris. For example, to store old skirting boards, slats and panels, you will need bags with a height of at least 150 cm. Of course, you can break panels and slats to fit them into more compact packages, but cleaning will take longer and become much more difficult.

No. 3. Trash bag strength

Tensile strength is the strength that a bag can withstand while maintaining its integrity. Average values ​​for materials used in production:

  • LDPE – 113-137 kgf / cm2;
  • PND – 186-343 kgf / cm2;
  • PSD – 245-373 kgs / cm2;
  • polypropylene – 204-408 kgf / cm2.

It turns out that if you slowly fill all four types of bags, then the first one that is made of LDPE will break, and the polypropylene product will last the longest. A whole range of values ​​is presented for each material, since the final parameter depends on the thickness of the product.

No. 4. Garbage bag thickness

The thickness is usually indicated for bags made of polyethylene. It can range from 9 to 250 microns: the higher this figure, the more durable and reliable the bag is in front of you. So you should pay attention not only to the material of manufacture. If you have two bags of the same size, and one of them is made of HDPE with a thickness of 9 microns, and the second is made of LDPE with a thickness of 40 microns, then the second will obviously withstand more.

No. 5. Loading capacity of the package

How much garbage can be removed with one bag depends on its size, material of manufacture and thickness. So, for example, a package with a thickness of 14 microns will withstand no more than 3 kg of cargo, and 30 microns – up to 20 kg. For construction waste, bags with a thickness of 60-120 microns are taken. On the packaging of such products, it may be indicated that they are extra strong, extra strong, or something like that.

LDPE bags can hold up to 25 kg of cargo, HDPE bags – up to 30-35 kg, polypropylene bags – up to 65 kg.

No. 6. Garbage bag bottom type

Another factor that greatly influences the carrying capacity of the bag is the type of bottom in the garbage bag. There are several options:

No. 7. Extra features

Not all construction waste bags are as ordinary and the same as we used to think. Additional features include:

  • the presence of ties and handles. The most convenient option is when you can simply pull off the ties and the filled garbage bag will be hermetically closed. As a rule, such bags do not have a bottom weld seam, so they can be considered the most durable and comfortable;

  • the presence of additives that make the package biodegradable. These additives do not affect the production process and the strength of the bag – they are simply mixed into the total mass, and then plastic bags are stamped. The advantage is that such a package decomposes in 1-1.5 years, while the usual one takes about a hundred years. Eco-bags cost a little more, but if you have ever seen on the Internet or on TV what mountains of plastic waste float in the ocean, then you probably shouldn’t be convinced of the need to use such products.

No. 8. Where to take the garbage?

The bags are selected, the garbage is stored. It remains only to get rid of the collected trash, that’s just where to put it. Do not secretly scatter over city containers at night. There are several ways to solve the problem:

  • if there is a place for the disposal of construction waste in the local area near the garbage containers, then the task is greatly simplified. Special containers are usually placed near new buildings;
  • find out if your management company has a contract for the removal of construction waste. If there is one, then at a certain time a container will be installed near the house, where you can load the garbage already collected in bags. In this case, the service fee will be minimal;
  • you can try to sell some of the construction waste. Buy, as a rule, broken brick, soil, sand, broken concrete, clay. The money is small, but you don’t have to worry about the export problem. In large cities there is a project called “Landfill”, which allows selling old furniture and unnecessary things;
  • contact a specialized company that will provide a container and take the collected waste to the designated landfill. The company’s services cost money, but you won’t have to think about where to find transport, and which landfill receives such waste;
  • try to take out the trash yourself. The most difficult option. You will have to find a suitable transport (trailer, minibus, truck), find out about the nearest landfills, find out if they can accept garbage from a private person, and how much it will cost. You will have to pay for the disposal of garbage.

If you just leave bags of construction waste near ordinary containers for collecting household waste, you can get a fine of up to 2,000 rubles if you are a private person, and up to 100,000 rubles if you are an organization. In this case, the garbage will still need to be removed according to the rules.
