Among the four types of packaging materials of paper, plastic, glass and
metal, paper and cardboard account for more than 40%of all packaging materials
in the world. As a packaging material, paper and cardboard have the advantages
that other materials cannot be compared. It not only has appropriate stiffness
and strength, but also has good elasticity and toughness. At present, many load
-bearing packaging on the market uses cowhide paper woven bags. However, the gas
resistance (oxygen) and wet resistance (water vapor) of kraft paper and woven
bags do not meet the requirements, especially for these two packaging products
with high performance. Therefore, aluminum foil composite leather paper bags
came into being.
Composite leather paper bags are often used to pack various chemical raw
materials, plastic particles, food additives and dry powder building materials.
Because it can be completely sealed around, it can effectively prevent the
pollution of content objects such as dust and other harmful substances such as
dust. It is not limited by the appearance of dangerous goods, and has strong
buffering and adaptability.
Commonly used for packaging of bulk solid dangerous goods. It is used for
chemicals such as cellulose, resin powder, salt, chemical additives. Compared
with other containers, multi -layer cowhide paper bags have better protection
and stronger buffer shock absorption performance. The structure is tight and
seamless, and it can cover dust and dust. In addition, due to the application of
many new technologies and the development of new varieties, kraft paper bags
have developed greatly in strength and moisture -proof capacity.

spontaneous combustion breakdown within 5 years is to be left toxic, odorless,
and no matter, so it will not pollute the environment, so the environment will
not be polluted, so the environment will not be polluted, so the environment
will not be polluted, so the environment will not be polluted. Protection is
also caused by this.
Three -layer cowhide paper bags are widely used. It can be divided into
leather, shoe non -woven fabrics, home decoration, home non -woven fabrics,
clothing non -woven fabrics, industrial non -woven fabrics, national defense
industry non -woven fabrics, auto industry non -woven fabrics, filter materials
non -woven fabrics, agricultural agriculture, agricultural Gardening non -woven
fabrics and other industries are not woven.
The characteristics of the three -layer cowhide paper bag products are:
Light quality. Three -fifths of cotton are thin and light, fluffy, and feel
good.
soft. It consists of fine fibers, and the dot -shaped hot -melt bonding
type, the softness of the finished product is appropriate.
