Description

LAMINATO PLASTICO MULTISTRATO MULTILAYER PLASTIC LAMINATE

DESCRIZIONE DESCRIPTION

L’invenzione consiste in un laminato plastico composto da tre stati di Film il cui primo strato è costituito da una pellicola di POLIESTERE (PET) con spessore mediamente di 12 micron e grammatura di 16,6 per Mq su cui viene steso inchiostro PVB con grammatura di 2 per Mq ed un adesivi bicomponente poliuretanico con gammatura 2 per Mq eh unisce un’ulteriore pellicola di LDPE (Polietilene Lo\ Density) di spessore 35micron e grammatura 32,2 al Mq; i secondo strato, di spessore complessivo di 276micron grammatura di 300 al Mq, nasce dall’estrusione di du pellicole di LDPE (Polietilene Low Density) i quali termosaldano formando bolle d’aria circolari mediamente 30mm di diametro; il terzo strato si compone nuovamente una pellicola di POLIESTERE (PET) di spessore mediamente di 12micron e grammatura di 16,6 per Mq su cui viene steso inchiostro PVB con grammatura 2 per Mq ed un adesivo bicomponente poliuretanico con grammatura 2 per Mq che unisce un’ulteriore pellicola di LDPE (Polietilene Low Density) di spessore 35micron e grammatura 32,2 al Mq. The invention consists of a plastic laminate composed of three layers of Film whose first layer consists of a POLYESTER (PET) film with an average thickness of 12 microns and a weight of 16.6 per m2 on which PVB ink with a weight of of 2 per square meter and a two-component polyurethane adhesive with a range of 2 per square meter and h joins an additional LDPE (Polyethylene Lo \ Density) film with a thickness of 35 microns and a weight of 32.2 per square meter; the second layer, with a total thickness of 276micron with a grammage of 300 per square meter, arises from the extrusion of two LDPE (Low Density Polyethylene) films which heat-seal forming circular air bubbles on average 30mm in diameter; the third layer is made up again of a POLYESTER (PET) film with an average thickness of 12micron and a weight of 16.6 per m2 on which PVB ink with a grammage of 2 per m2 and a two-component polyurethane adhesive with a grammage of 2 per m2 is applied which combines a '' additional LDPE (Low Density Polyethylene) film with a thickness of 35 microns and a weight of 32.2 per m2.

L’unione dei tre strati di Film plastici compositi su descritti rappresenta il “LAMINATO PLASTICO MULTISTRATO” oggetto del brevetto caratterizzato da una particolare leggerezza ma nel contempo di elevata resistenza alla trazione, torsione e strappo tanto da essere facilmente impiegato nel campo della produzione delle borse , borsoni in sostituzione del classico cuoio , pelle e tessuto avendo detto materiale una spiccata resistenza anche alla perforazione che garantisce la stabilità ed il mantenimento del punto di cucitura nel tempo. Detto prodotto inoltre, proprio perchè ottenuto dalla stratificazione dei tre Film su descritti dona al materiale un particolare effetto estetico che nella propria unicità e nella sua applicazione nel campo degli articoli da correggiaio, selleria e borse da viaggio rappresenta la vera innovazione, considerato inoltre, che detto materiale assume particolare lucentezza , trasparenza e spiccate doti di impermeabilità unite ad un basso costo di prodi The union of the three layers of composite plastic films described above represents the "MULTILAYER PLASTIC LAMINATE" object of the patent characterized by a particular lightness but at the same time high resistance to traction, torsion and tear so as to be easily used in the field of bag production , bags to replace the classic leather, leather and fabric having said material a marked resistance also to perforation which guarantees the stability and maintenance of the stitching over time. Moreover, this product, precisely because it is obtained from the stratification of the three films described above, gives the material a particular aesthetic effect which in its uniqueness and in its application in the field of strap articles, saddlery and travel bags represents the real innovation, also considered that said material assumes particular brightness, transparency and marked waterproofing qualities combined with a low cost of products
