Abstract
The utility model relates to a novel ethylene-Surlyn co-extruded film belonging to the technical field of packaging materials. The utility model is characterized in that the co-extruded film comprises an outer layer (1), an intermediate layer (2) and an inner layer (3); the outer layer (1) is a polyethylene layer; the intermediate layer (2) is an adhesive layer; and the inner layer (3) is a Surlyn layer. The novel ethylene-Surlyn co-extruded film has the advantages of good rigidity, high tensile strength, strong contamination resistance and low hot-seal temperature.
Description
(1) technical field
The utility model relates to a kind of novel ethene sarin co-extrusion film, and this film can be used as hot sealing layer is used for food, medicine etc. after compound with other material packing, particularly content technology of the package and requires canned, low-temperature heat-sealing, resistant to pollution high-speed packaging machine.Belong to field of packaging material.
(2) background technology
In food, drug packaging, the film that is usually used in sealing mainly contains PE, PP.Rising of conventional polyethylene film sealed temperature at 120 ℃, and an envelope temperature of conventional CPP film is 130 ℃.Can in polyethylene, add MPE etc. in the actual production and reduce the heat-sealing temperature of material, but the resistance tocrocking of MPE all is lower than the Surlyn material with hot sticky intensity.
Along with the variety of product such as food, medicine and used novel package machinery, multifunctionality proposes more more specifically requirements to packing.If any many inner packages,, and require the packaging material can low-temperature heat-sealing because at high temperature proterties changes easily; High-speed packaging machine reduces production costs, and becomes a kind of new trend owing to can enhance productivity greatly, then requires packing higher hot sticky intensity to be arranged to adapt to the requirement of high-speed packaging; More particles agent, powder product are widely used owing to being easy to be absorbed, and this formulation just requires packing that good antifouling property is arranged.Materials such as conventional PE, PP, MPE can not satisfy above requirement.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of good rigidly, pulling strengrth height, resistance tocrocking is strong, heat-sealing temperature is low novel ethene sarin co-extrusion film are provided.
The purpose of this utility model is achieved in that a kind of novel ethene sarin co-extrusion film, it is characterized in that: described co-extrusion film comprises skin 1, interlayer 2 and internal layer 3; Described outer 1 is polyethylene layer, and described interlayer 2 is a tack coat, and described internal layer 3 is the sarin layer.
The utility model has the advantages that:
(1) the utility model film good rigidly, pulling strengrth height can make packing bear bigger stretching; Its hot sticky intensity will be far superior to MPE, LLDPE, LDPE, and EVA etc., this makes packing that bigger advantage be arranged on canned and high-speed packaging machine;
(2) the utility model film antifouling property also is far superior to MPE, LLDPE, LDPE, EVA etc. can make packaging material have at heat cover under the situation of pollutions such as greasy and dust, inner package and still have good heat seal strength, guarantee the sealing effectiveness of package preferably;
(3) heat-sealing temperature of the utility model film is low, can satisfy the requirement that the special content thing can not bear the high temperature heat-sealing;
(4) the utility model film is produced having on the automatically controlled inflation film manufacturing machine, can the better controlled thickness deviation, thereby guarantee with other material compound after, the total thickness deviation of complex film is all smaller.
(4) description of drawings
Fig. 1 is the section structure scheme drawing of a kind of novel ethene sarin co-extrusion film of the utility model.
Among the figure:
Skin 1, interlayer 2, internal layer 3.
(5) specific embodiment
Referring to Fig. 1, a kind of novel ethene sarin co-extrusion film that the utility model relates to is made of skin 1, interlayer 2 and internal layer 3; Described outer 1 is polyethylene layer, and described interlayer 2 is a tack coat, and described internal layer 3 is the sarin layer.
Polyethylene layer can be made up of LDPE, LLDPE
Tack coat is EVA or EMAA or Surlyn (sarin).
The sarin layer can add a certain proportion of polyethylene, and poly addition scope is 0%～50% (percentage by weight).
Described co-extrusion film thickness is 30 μ m～80 μ m.
Three-layer thin-film forms by the three-layer co-extruded inflation film manufacturing machine blowing of device for cooling in having.The required pellet of trilaminate material enters screw rod after by the automatic weighting hopper weighing, is blown out by the film head through behind the heating and melting, and the tubbing that blows out cuts into two halves and rolling separately.The blowing process is noted strict control thickness deviation＜3um, and is follow-up compound steadily with other material to guarantee.
Claims (3)
1. novel ethene sarin co-extrusion film, it is characterized in that: described co-extrusion film comprises skin (1), interlayer (2) and internal layer (3); Described skin (1) is a polyethylene layer, and described interlayer (2) is a tack coat, and described internal layer (3) is the sarin layer.
2. a kind of novel ethene sarin co-extrusion film according to claim 1, it is characterized in that: described tack coat is EVA or EMAA or Surlyn tack coat.
