Abstract
This invention relates to a paper Al-molded liquid asepsis compound soft package material without sealing ribbons and aims at overcoming the shortcomings that sealing ribbons are easy to seep water, oil, oxygen and bacillis. The aim is realized by the following method: The material is composed of an outer film, paper, a blocking layer, an Al foil and an inner film, in which, the edges of the outer and inner films at a side place oversteps the edges of the paper, the blocking layer and the Al foil, and the edges of the outer and the inner films are combined to seal the edges of the paper, the blocking layer and the Al foil.
Description
Technical field
The present invention relates to a kind of compound package material, particularly the sealing strip free paper plastic-aluminum liquid asepsis composite soft packaging material.
Background technology
The otch section that has paper substrate not to be closed on the edge section of the packing that use in the prior art; will produce infiltration, oil and oxygen and bacterium when contacting with packed article thus infiltrates; therefore existing packing increase a sealing band outside needing in system box bag process; with paper side cut place heat-sealing protection; to reach paper layer section leak free purpose; but the sealing property of sealing band is difficult to reach fully the leak free effect; and because packing are to cut at the edge; thereby the resistance film at edge is destroyed easily, be difficult to reach the leak free purpose.
Summary of the invention
The objective of the invention is the sealing strip free paper plastic-aluminum liquid asepsis composite soft packaging material invented for the shortcoming that overcomes above-mentioned prior art.
For achieving the above object, adopt following technical proposals: the present invention is a sealing strip free paper plastic-aluminum liquid asepsis composite soft packaging material as shown in Figure 1, form by outer membrane 1, paper 2, barrier layer 3, aluminium foil 4, inner layer film 5, at least one side edge of this sealing strip free paper plastic-aluminum liquid asepsis composite soft packaging material, outer membrane 1, inner layer film 5 edges exceed the edge of paper 2, barrier layer 3, aluminium foil 4, and outer membrane 1 combines with the edge of inner layer film 5, with the edge sealing of paper 2, barrier layer 3, aluminium foil 4.
It is one of following that described outer membrane 1 can be selected for use: is the biaxial stretching film (BOPP) that raw material is produced with the polypropylene; With the polypropylene is the casting films (CPP) that raw material is produced; With the polypropylene is the blown film (OPP) that raw material is produced; With high density polyethylene (HDPE), low density polyethylene (LDPE), modification by copolymerization polyethylene is the blown film that raw material is produced; With high density polyethylene (HDPE), low density polyethylene (LDPE), modification by copolymerization polyethylene is the casting films that raw material is produced; With high density polyethylene (HDPE), low density polyethylene (LDPE), modification by copolymerization polyethylene is the showering film that raw material is produced; Nylon membrane; The polyester film.
It is one of following that described barrier layer 3 can be selected for use: polyethylene-polyvinyl alcohol copolymer (EVOH); Nylon membrane.
It is one of following that described inner layer film 5 can be selected for use: high density polyethylene (HDPE); Linear low density polyethylene; Metallocene PE; The modification by copolymerization polyethylene; The ion polyethylene.
Present technique adopts symmetrical mode of printing seal paper substrate both sides, in fixed position symmetry printing, printed patterns has the branch tangent line at the paper substrate edge, and utilizes reverse minute incision technology, not cutting of compound package material cut in the centre at the edge, thereby reach the purpose that edge resistance film is not destroyed.
Its production technology is at first to utilize outer membrane 1, barrier layer 3 and inner layer film 5 to stay heat sealable fillet in advance at least one edge when combining with paper 2 and aluminium foil 4, and add spacer material layer therein, it is combined with the ply of paper edge, in the middle of repeatedly the showering compound tense is sealed in the paper section, have only outer membrane 1 and inner layer film 5 thereby make at least one edge sections of packing, and do not have the paper substrate section.
Advantage of the present invention is covered by thermoplastic resin fully by the paper substrate section, packed article and paper substrate direct contact have thoroughly been stopped, reach this section and have barrier properties such as resistance is wet, choke, oil resistance, therefore in canned process, do not re-use sealing band and can directly make box or bag.

The specific embodiment
The present invention is described further below in conjunction with specific embodiment:
The present invention is a sealing strip free paper plastic-aluminum liquid asepsis composite soft packaging material as shown in Figure 1, form by outer membrane 1, paper 2, barrier layer 3, aluminium foil 4, inner layer film 5, at least one side edge of this composite soft packaging material, outer membrane, inner layer film edge exceed the edge of paper, barrier layer, aluminium foil, and outer membrane combines with the edge of inner layer film, with the edge sealing of paper, barrier layer, aluminium foil.The present invention can obtain in the following manner: at first be to utilize outer membrane 1, barrier layer 3 and inner layer film 5 to stay a fillet that can seal when combining by the combination of Fig. 1 with paper 2 and aluminium foil 4, in the middle of the showering compound tense is sealed in the paper section, have barrier properties such as resistance is wet, choke, oil resistance then thereby reach this section.
It is one of following that described outer membrane 1 can be selected for use: is the biaxial stretching film (BOPP) that raw material is produced with the polypropylene; With the polypropylene is the casting films (CPP) that raw material is produced; With the polypropylene is the blown film (OPP) that raw material is produced; With high density polyethylene (HDPE), low density polyethylene (LDPE), modification by copolymerization polyethylene is the blown film that raw material is produced; With high density polyethylene (HDPE), low density polyethylene (LDPE), modification by copolymerization polyethylene is the casting films that raw material is produced; With high density polyethylene (HDPE), low density polyethylene (LDPE), modification by copolymerization polyethylene is the showering film that raw material is produced; Nylon membrane; The polyester film.
It is one of following that described barrier layer 3 can be selected for use: polyethylene-polyvinyl alcohol copolymer (EVOH); Nylon membrane.
