Description
Technical field
The invention belongs to foamed plastic technical field, relate to a kind of packaging bag, particularly a kind of high-performance environment-friendly is closely knit moulds
Material packaging bag and preparation method thereof.
Background technology
Along with the fast development of China's economy, the purchasing power level of domestic resident and consumption wish the most progressively strengthen, consumption
Trend is improved the quality of living by idea further.Plastic packaging bag brings conveniently to our life, but this facilitates for the moment
But bringing permanent harm, plastic bag recovery is worth relatively low, and in use except causing " white pollution ", it there is also
Potentially hazardous.Plastic construction is stable, is difficult to be degraded by natural microbial bacterium, does not separates for a long time in natural environment.This just anticipates
Taste waste plastic garbage if do not reclaimed, and will become pollutant in the environment and is permanently present and constantly accumulates, and can make environment
Become high risks.
Being rooted in the hearts of the people of current environmental protection concept, increasing people constantly explores the plastics with degradable, environment-friendly function
Packaging bag.Meanwhile, sealing bag is to be passed through blowfilm shaping, hot-cutting machine bag, made by polyethylene and high pressure Hi-fax
Planting the plastic bag that can repeat sealing, sealing bag can be used for the exterior and interior packing of various small article；By the raw material production of food stage
Sealing bag can deposit various snack food, Folium Camelliae sinensis, marine product etc., can moistureproof, waterproof, insect protected, prevent thing to be scattered.
Polypropylene is polymer nontoxic, that odorless, tasteless milky are highly crystalline, and density only has 0.90-0.91g/m3, it is
One of at present the lightest in plastics kind, it is particularly stable to water, and the water absorption rate in water is only 0.01%, molecular weight about 80,000-
150000, good moldability, but shrinkage factor is big, and polyacrylic chemical stability is fine, outside decapacitation is corroded by concentrated sulphuric acid, concentrated nitric acid, right
Other various chemical reagent are the most more stable.
Merlon is a kind of water white transparency or the firm and tough and tensile material of pale yellow transparent, satisfactory mechanical property, stretching
Intensity, rigidity, wearability and electrical insulating property are also fine, and resistance to diluted acid, oxidant, reducing agent, oils, aliphatic hydrocarbon are weak to purple
Outer light, the most alkaline-resisting, Merlon is made together with polypropylene packaging material by market and does not the most occur.
Sealing bag acid and alkali resistance corrosive nature on market does not reaches requirement so that it is purposes is the most limited, closely knit in order to improve
The performance of bag, alleviates the plastic packaging bag pollution to environment, now provides a kind of new scheme.
Summary of the invention
It is an object of the invention to provide a kind of high-performance environment-friendly dense plastic materials packaging bag and preparation method thereof.
