About green packaging

In recent years,plastic flexible packaging industry has developed rapidly, and it has also strongly promoted the progress of food, daily chemical and pharmaceutical industries. The progress of these industries has in turn further stimulated the market demand for plastic flexible packaging films.  With the continuous improvement of materials and processing technology, gravure plastic flexible packaging is playing an increasingly important role in many fields. People's lives are inseparable from shopping bags, commodity bags, garbage bags, and refrigerator fresh-keeping bags; and industrial product packaging ,Household daily necessities packaging, clothing packaging,pharmaceutical packaging also use a large number of plastic flexible packaging films.

With the impact of the wave of environmental protection, consumers have put forward higher and higher requirements for commodity packaging.  Green packaging is an international environmental protection
The needs of the development trend also represent the development trend of the packaging industry in various countries. It is to improve the market competitiveness of products and avoid new
One of the important contents of trade barriers.  In line with this, the greening of plastic flexible packaging films has also become one of the important development trends.
one.  There is currently no fully unified definition of green packaging.  Generally speaking, it can be recycled, reused or
Moderate packaging that degrades and corrodes, and does not cause pollution to the human body and the environment in the entire life cycle of the product, is called green packaging.
The most important meaning of green packaging is to protect the environment, and it also has the meaning of resource regeneration.
Strengthening recycling and reuse and realizing the ecological cycle of packaging waste are the most powerful measures to reduce environmental pollution.
During its entire life cycle, green packaging follows the economic activity principle of "reduction, reuse, and recycling" of circular economy, so as to minimize the impact of packaging on the environment.  Today, the protection of blue sky, clear water and green resources has become the common goal of human life.
Kraft paper, used as packaging material.  Intensity is high.  Usually yellowish brown.  Semi-bleached or fully-bleached cowhide
The pulp is light brown, cream or white.  Quantitative 80~120g/m2.  The fracture length is generally more than 6000m.  Strong tear resistance degree, work of rupture and dynamic strength are very high.  Mostly roll paper, but also flat paper.  Using sulfate softwood pulp as raw material, after beating Pulp, made on a Fourdrinier paper machine.  It can be used as cement bag paper, envelope paper, glue-sealed paper, asphalt paper, cable protection paper, insulating paper, etc.

A long time ago, "kraft paper" was really made of calf skin.  Of course, this kind of "kraft paper" can only be done now
It is only used when the drum skin is used; and the kraft paper you use for wrapping books is made of coniferous trees after people have learned the technology of papermaking.
The wood fiber is chemically pulped, then put into a beating machine for beating, and then sizing materials, dyes, etc. are added, and finally Paper is made into paper in a paper machine.  Because the color of this paper is yellowish-brown and the paper is tough, it is very similar to cowhide, so people call it the Kraft paper.  In fact, the manufacturing method of kraft paper and ordinary paper is not much different.  Why is kraft paper stronger than ordinary paper?  This is mainly because the wood fiber used in making kraft paper is relatively long, and when cooking wood, it is treated with caustic soda and sulfide alkali chemicals, so that the chemical effect they play is relatively relaxed, and the original strength of wood fiber is The damage suffered is relatively small, so the paper made of this pulp is closely related to the fibers, so the kraft paper is very strong.
