Description
Technical field
This utility model is related to packaging material field, specifically a kind of nine layers of co-extrusion high temperature steaming deep drawn film.
Background technology
A kind of raw material is expressed on Manufactured another kind of thin film or by Manufactured variety classes in the processing of thin film
Thin film be mutually bonded to together and become multilayer film, this product is referred to as composite membrane.The material great majority of composite membrane are plastics,
But also can be with paper, metal forming (usually aluminum) or fabric etc..The basic demand of composite membrane is exactly to have good between layers
The cementability overall performance to ensure packaging.Additionally, composite membrane is used for packaging for foodstuff, to use in the processing of composite membrane
Adhesive, the selection of its solvent and gluing technique etc. will meet corresponding sanitary standard and require.
Co-extrusion film has most of feature of composite membrane, due to be between layers by hot melt combine and without the need for adhesive,
Therefore it is relatively reliable to the wholesomeness of packaging for foodstuff co-extrusion film.
The characteristics of coextruded film has stretching in process, can accordingly improve intensity after plastic tensile, it is also possible to
It is middle to add the plastic materials such as nylon, metallocene polypropylene so as to possess and exceed general plastics packed combined strength bination, do not exist
Delamination phenomenon, 121 DEG C of cookings of high temperature resistant are good, and heat sealability is excellent.
PVDC, scientific name are " polyvinylidene chloride ", and it is a kind of nonpoisonous and tasteless, safe and reliable high barrier material, except tool
Have outside the general performance of plastics, also with oil resistivity, corrosion resistance the features such as, can be widely applied to the industries such as packaging for foodstuff.This
The MA-VDC raw materials for being used exclusively for the production of co-extrusion film used in utility model.
Utility model content
Cannot use in the packaging of 121 DEG C of high temperature sterilize products for above-mentioned existing PVDC raw materials coextruded film,
The problems such as having significant limitations, this utility model provide a kind of nine layers of co-extrusion high temperature steaming deep drawn film.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of nine layers of co-extrusion high temperature steaming deep drawn film, described deep drawn film be followed successively by from outside to inside PP layers, Tie1 layers,
PA layers, Tie1 layers, PP layers, Tie2 layers, PVDC layers, Tie2 layers and PP layers.
The thickness difference of the PP layers, Tie1 layers, PA layers, Tie1 layers, PP layers, Tie2 layers, PVDC layers, Tie2 layers and PP layers
For 10 ~ 15 μm.
The beneficial effects of the utility model：
Nine layers of co-extrusion high temperature steaming deep drawn film that this utility model is provided, it is possible to use in 121 DEG C of high temperature sterilize products
Packaging on, high temperature meat product packaging can use PVDC high-resistant diaphragms；PP is arranged on outer layer contributes to the life of downward-blowing water-cooling equipment
Produce, nine layers of co-extrusion high temperature steaming deep drawn film that this utility model is provided can tolerate 121 DEG C of steaming and decocting requirements of high temperature；This practicality is new
The preparation method of nine layers of co-extrusion high temperature steaming deep drawn film that type is provided, what PVDC extruding layers setting one was connected with extruder
Runner, runner form pincer in center, make PVDC runners in forming process most short；The PP extruding layers, PA extruding layers
And the runner of Tie extruding layers, take one-to-two, two point four, four point eight of dish-shaped short helical flow path；Nine layers of co-extrusion height of gained
Warm steaming and decocting deep drawn film is resistant to 121 DEG C of high temperature.
Description of the drawings
Fig. 1 is the structural representation of nine layers of co-extrusion deep drawn film；
Runner schematic diagrams of the Fig. 2 for PVDC mold layers；
Fig. 3 is one-to-two, and two point four, four point eight of labyrinth type is without dead angle runner schematic diagram.
Specific embodiment
This utility model is further elaborated with reference to specific embodiment.
A kind of nine layers of co-extrusion high temperature steaming deep drawn film, described deep drawn film be followed successively by from outside to inside PP layers, Tie1 layers,
PA layers, Tie1 layers, PP layers, Tie2 layers, PVDC layers, Tie2 layers and PP layers.
The thickness difference of the PP layers, Tie1 layers, PA layers, Tie1 layers, PP layers, Tie2 layers, PVDC layers, Tie2 layers and PP layers
For 10 ~ 15 μm.
A kind of preparation method of nine layers of co-extrusion high temperature steaming deep drawn film as above, the deep drawn film adopt multilamellar
Prepared by co-extruding mould, the multi-layer co-extruded mould has plug and core rod, and the plug periphery arranges multilamellar to be used to extrude difference
The mold layer of material；Runner from molten thermoplastic entrance to annular extrusion outlet is set in the mold layer；PVDC is squeezed
Go out layer and one runner being connected with extruder is set, runner forms pincer in center；The PP extruding layers, PA extruding layers and
The runner of Tie extruding layers, takes one-to-two, two point four, four point eight of dish-shaped short helical flow path.
This utility model is illustrated with reference to accompanying drawing, the structure of nine layers of co-extrusion stretched film as shown in Fig. 1, from outside to inside according to
It is secondary for PP, Tie1, PA, Tie1, PP, Tie2, PVDC, Tie2, PP.This utility model adopts a kind of multi-layer co-extruded moulds of PVDC
Prepare, as shown in Figure 2 and Figure 3, the mould has multiple annulars or conic mandrel bar, and the plug periphery arranges multilamellar to be used for
The mold layer of extrusion different materials；Stream from molten thermoplastic entrance to annular extrusion outlet is set in the mold layer
Road；Runner design of the PVDC layers using single entry, runner form pincerlike state in center；PVDC is made in forming process
Runner is most short.
All it is PE raw materials and EVA etc. new with the technical application of PVDC raw material co-extrusions in prior art, this thin film can not
So as in the packaging of 121 DEG C of high temperature sterilize products, have significant limitations, in order to high temperature meat product packaging can be used
PVDC high-resistant diaphragms, this utility model provide this nine layers of high temperature steaming type high-barrier PVDC co-extrusion film formulation structure.PP is arranged
Contribute to the production of downward-blowing water-cooling equipment in outer layer, do not use PE and EVA raw materials to be just because that these materials cannot tolerate high temperature
121 DEG C of steaming and decoctings are required.
