Fig. 1 is a kind of structural representation packed with flame retardant plastics film.
Reference numeral: 1, polyethylene polymer PE layer; 2, polycarbonate layer; 3, polyamide PA layer; 4, ethylene-vinyl alcohol copolymer EVOH intermediate layer; 5, polyolefin A DMER adhesive-layer.
Detailed description of the invention
With reference to Fig. 1, a kind of packaging flame retardant plastics of the utility model film is described further.
As shown in Figure 1, a kind of packaging uses flame retardant plastics film, comprise ethylene-vinyl alcohol copolymer EVOH intermediate layer, and coextru-lamination is in the external composite layer of both sides, ethylene-vinyl alcohol copolymer EVOH intermediate layer, described external composite layer comprises the polyethylene polymer PE layer, polycarbonate layer and the polyamide PA layer that are combined with each other, and described polycarbonate layer and polyamide PA layer are located between ethylene-vinyl alcohol copolymer EVOH and polyethylene polymer PE layer.
Preferably, described polycarbonate layer is located between polyethylene polymer PE layer and polyamide PA layer, also polyethylene polymer PE layer can be located between polycarbonate layer and polyamide PA layer, impact strength can be reduced when this vibrational power flow and reduce flame retardant effect to a certain extent, and there is stronger fire resistance and shock resistance due to polycarbonate, therefore polycarbonate layer is arranged on outside polyamide PA layer, strengthen anti-flammability and impact strength.
Preferably, polyolefin A DMER adhesive-layer is provided with between described polyethylene polymer PE layer and polycarbonate layer and between polycarbonate layer and polyamide PA layer, because the number of plies is too much therefore bonding by polyolefin A DMER viscose glue, strengthen the connectivity robustness between a plastic sheeting.
Preferably, described polycarbonate layer is fire retardation PC.Fire retardation PC has better flame retardant effect, strengthens a kind of anti-flammability of packing with flame retardant plastics film of the utility model.
Preferably, described polyamide PA layer thickness is greater than polycarbonate layer thickness and is greater than ethylene-vinyl alcohol copolymer EVOH intermediate layer thickness and is greater than polyethylene polymer PE layer thickness and is greater than polyolefin A DMER adhesive-layer thickness.Because polyamide PA layer Main Function is to strengthen mechanical strength therefore to arrange the thickness of polyamide PA layer maximum, its flame retardant effect event polycarbonate layer of the thickness effect of polycarbonate layer can not be excessively thin, the Main Function in ethylene-vinyl alcohol copolymer EVOH intermediate layer is to intercept, the Main Function of polyethylene polymer PE layer is the effect of printing and its nontoxic odorless, therefore can be thinner relative to polyamide PA layer and polycarbonate layer, save material cost, polyolefin A DMER adhesive-layer is blocked up can be affected bonding effect and easily produce residue.
Preferably, the thickness of described polyethylene polymer PE layer is 13-79um, and the thickness of polycarbonate layer is 35-90um, and the thickness of polyamide PA layer is 30-100um, the thickness in ethylene-vinyl alcohol copolymer EVOH intermediate layer is the thickness of 22-78um, polyolefin A DMER adhesive-layer is 10-48um.Each material layer in above scope can reduce production cost a kind of packaging of guarantee the utility model with under the prerequisite of each function of flame retardant plastics film.
By adopting technique scheme, because ethylene-vinyl alcohol copolymer EVOH presents excellent blocking effect to gas, smell, spices, solvent etc.; Polyamide PA has good mechanical property, heat resistance, mar proof, chemical proofing, self lubricity and certain anti-flammability; Polycarbonate has high strength and coefficient of elasticity, high impact, heigh clarity, anti-flammability, wear-resisting; Polyethylene polymer PE has odorless, nontoxic, feel ceraceous, there is excellent resistance to low temperature, chemical stability is good, the erosion of the most of soda acid of ability, is applicable to the Product labelling that the performances such as water resistant, oil and chemical substance are higher, the printing of vast source often by this materials application in advantages such as cosmetics, shampoo, washing and other household chemicals labels in use having moisture resistance, anti-extrusion to require; And polycarbonate is due to not ultraviolet resistance, not resistance to highly basic, therefore polyethylene polymer PE is set outside polycarbonate layer, the utility model is made to have higher flame retardant effect by the dual anti-flammability of polycarbonate and polyamide PA, polyamide PA has higher mechanical strength simultaneously, ethylene-vinyl alcohol copolymer EVOH intermediate layer is arranged at the middle fragility defect then improveing ethylene-vinyl alcohol copolymer EVOH and exist.
The above makes preferred embodiment of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
