Fill a boxing bag with many materials. Some of them cost almost nothing, others have a very impressive cost. But besides that, all materials for packing a boxing bag have their advantages and disadvantages.
Types of Fillers
Manufacturers for packing bags usually use:
tanning wastes — rags of various fabrics or batting (rags) —tyrsu — rubber crumb — sawdust — sand — expanded clay — granules of polyethylene.
House craftsmen at times use foam rubber, cotton-like heat insulators, rugged tires and old things. In principle, all of these fillers are ordinary household waste that has the same properties as industrial fillers. The only difference is that it is cheaper and easier for the manufacturer to conclude a contract for the supply of waste with a tanning workshop or a clothing factory than collecting old mattresses and clothes at home.
Punching Bag Requirements
A good projectile should have the following qualities: moderate softness, ability to quickly restore shape, not too large mass, but decent mass so as not to hang out, and the ability to absorb shock loads. During training, arms and legs should bounce off the projectile, but not be injured. A good selection of punching bags with various fillers can be found on the site …
Distinctive features of fillers
Leather is considered one of the best fillers, it has an optimal weight and shock-absorbing properties, sufficient softness and resistance to crushing. Since the skin is quite tough, it is often supplemented (with a rag) with a cotton or synthetic fabric or scraps of insulation for clothes. Even without skin, these materials can hold volume and retain their properties for years, even with the most intense workouts.
The rubber crumb combines all the advantages of leather and rags and the optimal mass, if the pear seems too light, its mass is “finished” with sand. Used tires can become a home replacement, but they need to be finely crushed to a size of 1-1, 5 mm. Polyethylene granules have the same properties, but are more difficult to find on sale.
Filling out of sand is the cheapest and most inconvenient option; small particles quickly get off and the shell turns into stone. Although, if necessary, this material is used together with others to increase mass. Tyrsa and sawdust have the same disadvantages as sand.
Expanded clay is used when sufficiently solid filling is required. Due to the stiffness on it, sensitivity in fists and other places during training is faster lost. Lightness, if necessary, is compensated by the addition of sand.
