Main application fields of pulp molded products
Plant fiber molded products are also called pulp molded products, which are mainly used in food packaging, also called meal packs, and industrial packaging, also called work packs. In fact, the process of pulp molding is also a kind of three-dimensional papermaking, and its application field can not only be summarized by meal bags and work bags. For example: pulp molded three-dimensional wallpaper belongs to the field of building springs, pulp molded cow plugs and sheep plugs belong to the field of animal husbandry, pulp molded hangers and pulp molded shoe linings belong to the field of clothing and shoemaking, etc. Pulp molded products span industry boundaries.
However, at present, pulp molding products are mainly meal bags and work bags, which are environmentally friendly packaging products molded from degradable plant fibers. Pulp molded meal packs, that is, environmentally friendly food packaging products are degradable plant fiber molded environmentally friendly food packaging containers, mainly including lunch boxes, instant noodle bowls, plates, cups, plates, and fresh-keeping dishes.
Degradable plant fiber molded environmentally friendly packaging products are made of fast-growing plant fiber cardboard (bagasse, wheat straw, wheat straw, bamboo, etc.) or recycled paper from waste paper products. The material is poured into the three-dimensional mold, and various special-shaped blanks are made by vacuum dehydration, and the three-dimensional paper products are compression molded on the special mold for shaping.
The main application areas of the product
Pulp molding environmental protection packaging product is a new type of green packaging material that is widely used.
(1) Environmentally friendly food packaging
In addition to fast food utensils, many edible semi-finished products, cooked food and convenience food can use environmentally friendly packaging, such as vegetable trays, instant noodle bowls, etc. Environmentally friendly packaging products are not only convenient and quick to use, but also clean, hygienic, recyclable, and meet the requirements of environmental protection and human health. The use of environmentally friendly paper-based materials on food packaging has become an international practice.
(2) Packaging of environmentally friendly medicines and health care products
The biggest problem in the use of traditional medical equipment is that the disinfection is not thorough and it is easy to form cross-infection. If the environmentally friendly products of this project are used, such as disposable trays, spittoons, bedpans, body pads, splints, etc., not only can the disinfection process be eliminated. , save labor, and its waste can be directly incinerated, plus non-toxic, no side effects, these have brought a lot of convenience to medical care.
(3) Packaging of environmentally friendly home appliances and daily necessities
At present, most of my country's electrical products use foamed plastic as the lining material, but the import of such packaging has been banned abroad, and my country's lining packaging must take the road of "replace plastic with paper". The pad made of paper mold material not only has the characteristics of plasticity and strong buffering force, but also has a concise production process and will not cause environmental pollution. Such products have strong adaptability and great production potential.
(4) Packaging of environmental protection industrial building materials
Some of the internal and external packaging materials and building materials required for industrial products must have high strength and compressive stress, and some must have moderate softness and elasticity to meet the requirements of gravity impact and pressure. Due to the physical strength and physical properties of plant fibers, paper mold environmental protection industrial building materials packaging materials have significant advantages in stiffness, tensile strength, tear strength, bending strength and antistatic protection. It can be widely used in strong transportation packaging, industrial product liners, fragile product spacers, plant fiber environmentally friendly ceilings, etc.
(5) Environmental protection military and special product packaging
Arms products are afraid of collision, avoid static electricity, and hate moisture, and require extreme caution in their packaging, transportation and storage. The paper mold material produced in this project has strong plasticity and can be moisture-proof and anti-static. If special additives are added, it can also prevent shallow radiation. It is used for the packaging lining of ammunition, explosives, gunpowder and other items, which can greatly reduce the danger of arms management. .
In addition, the paper mold environmental protection packaging materials can also be added with different additives and applied in the paper sizing process, so that different materials have different professional properties, including water-blocking (moisture-proof) performance, oil-proof (heat insulation) performance, anti-static performance, anti-shallow radiation performance, so that the use of paper mold environmental protection packaging materials has been greatly expanded.
Environmentally friendly home appliances and daily necessities packaging, before, most of our electrical products used foam plastic as the lining material, but now foreign countries have banned the import of such packaging, my country's lining packaging must take the road of "replacing plastic with paper" . The pad made of paper mold material not only has the characteristics of plasticity and strong buffering force, but also has a concise production process and will not cause environmental pollution. Such products have strong adaptability and great production potential.
