Abstract
An oriented film, either complex or non-complex, whose properties include stretchability, tracer printability and peelability. It is perfectly adapted to use in the protective packing and vaccumize packing of display containers for high-quality products, particularly foodstuffs.
Description
The present invention relates to method, in particular for the packing of high quality food with the display containers of an a kind of stretchable and peelable film protective package or a vacuum-packed exquisite product.The invention still further relates to a kind of strippable packing film of upholding; be printed on maybe on this film and will be printed on several colors; printing method has aniline printing method (flexography) or colorful photolithographic process; especially three primary colors method or four primaries method; also relate in skin packaging (or claiming skin-packaging) (skin packaging) industry and use a kind of stretchable and peelable film to a kind of high quality of products, especially the display containers of food carries out protective package or vacuum packaging.
In the emporium, sell food requirement and have the ornamental packing of special quality, so that embody the value and the freshness of product in compellent mode.
Usually, these products are given in dish or the dish in moving mode, are coated with the last film of one deck high grade of transparency then on it, and it has coated product, just as its second layer epidermis.
The typographic(al) mark of one autohension is placed on the film, and its purpose is to transmit a kind of advertising message of graphic or character property, also comprises requisite information on it, such as weight, composition, and the trade mark and effectively selling the time limit etc.
High-grade product is more suitable in this packing, as to selected cube meat, sootiness ham piece, meat gruel, fillet or game lean pork taken under the spinal column of a hog.
This plastic sheeting that is adopted should have certain heat and mechanical characteristics, should satisfy following several requirements at least:
-good air-tightness and the close property of water vapour is to guarantee long-time preservation;
-be easy to open (although having the anti-permeability of height to require) to joint at joint;
-have a moving expression power;
The vivid property of-height;
-surface condition is suitable for pasting the typographic(al) mark of self-adhesion in the above;
The heat stability of-height.
People know that can be made into (or mixing) squash type surface film with strippable non-conductive polyethylene is used for the display containers of meat and other food from file EP-A-0328245.
These co-extrusion pressure type surface films, the outline that can ideally contain packaged product owing to its relative compliance structure does not have a bit fold.They form the effective insulation to air.
Because they have very strong elasticity, add the characteristic of manufacturing process and employed resin, these materials do not have characteristic necessary and enough printings of do thereon, for example, the colorful film mechanical of three primary colors or four primaries need use printable substrate, it has good dimensional stability on printer, this dimensional stability can ideally define different colors, and obtains the constant mechanical spacing by wrapping machine applied in printing.
As a result, because its big extensibility makes the substrate of making as the usefulness co-extrusion pressure mode of " epidermis " now be not suitable for doing the film mechanical printing with said method.
In addition, the location of the print gap on the wrapping machine is very unstable.
What also note that is, can only print on the surface of these films, and this just greatly reduces the attractive force that its brightness has also influenced product.Being difficult to the seal China ink is suitably adhered on the film also is the problem that should note.
Just because of this; be necessary to be affixed in the substrate with the printed mark of autohension; so that product has more commercial appeal have again simultaneously in sign subscript explicit law and restrain desired information; this essentiality forces the end user to invest the automatic decals will machine of configuration on product production line; this will make work capacity that considerable increase is arranged; and influence output speed, especially when shutting down dehorn will paper tape
Nowadays in film industry, to doing colorful film mechanical printing thereon, the demand of especially available three primary colors or four primaries materials printed is very big.Have again, can know various uses, have directedly or nondirectional,, be used as the skin material of the packing of non-food stuff series products from PVA (polyvinyl alcohol) compacting or compacting altogether to film from patent WO95/21105 people.
This document is mentioned some composition can be water-soluble, can make substrate present porous low-quality state, so just do not possess air-tightness.
In view of this, this system can not be used for preserving food, because the time of food on shelf reaches 21 to 90 days more than, the ambient humidity of its experience is very high, and storage temperature is between 4 ℃ to 7 ℃.
Saying nothing of material can be water-soluble in the time of 40 to 100 ℃, especially is dissolved in this fact of cold water and makes it be unwell in the wet environment to use.
In view of above-mentioned all technical limitation of material and in food service industry growing to the demand of " spike printing epidermis " (tracerprinted skin), the present invention includes and select a kind of high grade of transparency, can uphold strippable single orientation or amphiorentation film, and with this film to exquisite product, especially food, carry out film and vacuum packaging, with in a dish or the basin of Heat forming with moving mode display of products.
The film that the present invention includes with a kind of high grade of transparency carries out film and vacuum packaging to product especially food, and purpose is to make product to be given in the basin of a dish or Heat forming in moving mode.The original flat last narrow that covers of the basin of Heat forming is moulding through heating only.
According to a feature of the present invention, the film that can uphold is directive, be printed on maybe at the back side of film and will be printed on content, printing method is the colorful film mechanical printing of aniline printing or three primary colors, four primaries, and film is by (the DuPont de Nemours of for example De Namosi of Du Pont company
) Mylar that provides
M45 specification (scribbling the PVDC of 1 μ) or Mylar
The polyethylene terephthalate of P25 specification.The directive nylon film that also available a kind of directive polypropylene film or single shaft or twin shaft extend.
