Description
Technical field
The present invention relates to packaging material production technical field, specially a kind of production technology of EPE pearl wool.
Background technology
Polyethylene foam cotton is non-crosslinked hole-closing structure, also known as EPE pearl wool, is a kind of packaging material of novel environment friendly.
It produces countless separated foams through physical blowing by low density polyethylene (LDPE) fat and formed.It is not only not dirty due to extraordinary advantage
Contaminate environment, and can repetitiousness recycle, therefore EPE pearl wool expanded material is a kind of new, Chaoyang unabated material forever.
Application is continually developed in propulsion and product over time, and EPE pearl wool expanded material will obtain in terms of packing and filling materials
It is applied even more extensively.Current EPE pearl wool expanded material production, it is more flourishing in the Delta of the Pearl River, using the material each
It is more universal in each industry of row, and to producing and obtaining good economic benefit using the material enterprise, achievement is very notable.It is but real
Line enterprise of having been put into production on border far can not meet the needs of domestic all trades and professions market, moreover domestic still have at many provinces and cities
In blank area, it is badly in need of this new material and fills up packaging, fills the needs of industry.
The antishrinking agent list glyceride that pearl cotton talcum material and food are drawn, whole production process is physical change, so EPE is
Nontoxic, environmentally friendly, EPE has higher elasticity, and rich in tough without crisp, is more advanced, environmentally friendly built-in in the world at present
Material.Pearl cotton is particularly in terms of packing with other industrial cut stocks, and it is more preferable with material performance than traditional, and cost is lower, shelves
It is secondary higher, it is elegant in appearance, it is better.Its other its more aobvious wide world in terms of agricultural byproducts packing timber.Pearl simultaneously
Cotton foam sheet can also carry out deep processing, only need to prepare pearl cotton coating machine, compounding machine, be covered on the surface of EPE sheet materials
HDPE film, aluminizer, plastic-coated paper, plastic-coated fabric etc. is closed, the EPE sheets after overlay film, not only improves mechanical strength, but also can carry
High original various performances and the various patterns of attached printing, word, expand products propaganda dynamics.And can be wide to the sheet material after compound
General liner bedding and padding for being applied to case liner, life vest, heat-insulated, moistureproof camp etc. etc., EPE pearl wool economic benefit is with double increasing
It is long.
The existing EPE pearl wool product surface produced with general production technology into poroid, ease up punching performance by performance that its is pressure-resistant
