Description
The present invention relates to a kind of novel type of beverage infusion packing, this packing allows its infusion product inner contained or that provide to be labelled by the logo or the trade mark of printing.Particularly, described infusion product is coffee or tea.This beverage soaks packing and is made by paper or other non-woven material that is used for beverage packaging, can be used for all coffee ﹠ teas and filter and package, as tea bag, hard beanpod (pods), soft beanpod, coffee pouch and wherein container contain the system of the paper of being with tea, coffee or other infusion beverage.Described beverage packaging can be to comprise " one glass " the type bag that is enough to provide disposable service soak-out material such as tea, or comprises " repeatedly brewing " type bag that is enough to provide once above service soak-out material.The invention enables printing to carry out on the packaging, and can not cause injurious effects, also do not have and introduce the risk of harmful substance in the product the integrality of packing.
Beverage soaks the beverage precursor material (as tealeaves or coffee powder) that is encapsulated in papery bag, pouch, the folliculus etc. (for simplicity, this paper is referred to as bag), and its basic weight is generally 9～40g/m
2Described paper or other non-woven material are often referred to " thin paper " or " tea bag thin paper ", typically can make by traditional wet laminated (wet-laying) technology, in this technology, at least one deck is into the aqueous suspension of paper fiber and is taped against mobile water permeability to become on the paper screen cloth, thereby then water emptying from screen cloth is produced paper.Paper can be " heat-sealing " type or " non-heat-sealing " type.
Can use identical method or utilize other paper manufacturing technology such as melt blown technology (melt blown) shop layer, thereby increase the second layer or more layer.
The paper web that is suitable for forming beverage packaging such as tea bag and comprising the polypropylene gauze is made by known dried laminated technology in the field.These materials also can be printed according to the present invention.
The invention still further relates to based on used conventional paper in tea bag and the manufacturing of coffee immersion packing or based on heat-sealing type that contains high percentage wood pulp paper and non-heat-sealing type beverage and soak packing production, high percentage wood pulp described herein has unique advantage because of its wood pulp content is high.No matter under any situation, paper is all handled introducing required characteristic, but paper also can randomly comprise the antioxidant desired according to the present invention or other additive.Thereby the present invention is packaged as and has good storage life when the consumer facilitates.
Thin paper can be a heat-sealing type, and it has introduced thermoplastic fibres and by with two-layer thin paper heat-sealing and preparation of drinks soaks packing.Scheme as an alternative, thin paper can be non-heat-sealing type, it produces the closure seam of beverage infusion packet by the method for using mechanical action need not seal as curling.
Heat seal tissue comprises one or more layers paper web.The individual layer heat seal tissue contains cellulosic and thermoplastic fibre.When paper web has when two-layer or more multi-layered, one deck can contain cellulose fibre, and other layer can be introduced the thermoplastic fibre that forms heat-sealing matrix.In another arrangement mode, internal layer (structure sheaf) comprises cellulose fibre and thermoplastic fibre.The thermoplastic fibres that carries provides stronger heat-sealing between two paper webs of thin paper, because thermoplastic molding's heat-sealing is an intact part of structure sheaf.Forming the outer field second layer or the 3rd layer is insulation material layer, and its major function is that the cylinder of protection processing machine does not influence and contains thermoplastic structure's layer during handling.
Non-heat-sealing type paper comprises the paper web of single layer fibre matter fibrous material usually.But such paper web can be by two-layer or more multi-layered formation.Such packing packs by paper is folding and formation mechanical closure seam.
Usually need have certain pattern when producing thin paper.Can use the sample of various patterns, soak abbreviation and/or little mark of packing manufacturer as beverage.Scheme as an alternative, pattern can comprise the dot of repetition or rhombus " point " thereby produce the effect of perforation in thin paper.
The whole bag of tricks that produces pattern in thin paper is known.
One of this type of technology is that the fluid jet pattern forms.In this technology, in wet laminated manufacture process,, paper web forms pattern when paper forms on the screen cloth when also utilizing fluid jet (normally water) directly to face toward paper web.More particularly, becoming to place on the paper screen cloth cylindrical pattern formation screen cloth that rotates along trunnion axis, the wall of screen cloth generates pattern by limiting hole penetrates.It is fluid jet pressure source (supplying with as water) that cylindrical pattern forms in the screen cloth, and it forms hole and outlet in the screen cloth so that cross pattern with mode of jet radially outwardly, thereby forms the pattern in the paper web.
But this technology has such shortcoming: owing to destroyed the fibre structure of paper web, compare with not carrying out the mechanical strength that the operation of fluid jet pattern-forming obtained, its mechanical strength has descended.Paper web may split under extreme case.In addition, the filtering property of paper web may be relatively poor, and this can make beverage precursor material fine powder flow out from final immersion bag.
And, in becoming the paper screen cloth, forming the water of wet shop suspension, the water jet pattern formation technology also needs a large amount of water.
Pattern, also can be produced by the ledge (protrubence) (being also referred to as " bulge ") that becomes the paper screen cloth to give prominence to from the preparation process of wet shop when constituting by the point that repeats (to produce the effect of boring a hole).The interior fibre density (being the fiber number of unit are) in the zone of the paper that forms is lower than the density in other zone on the bulge, thereby produces the effect of pattern.But this technology has such shortcoming: the local open zone that the silk screen bulge produces and the decline of fibre density cause (I) locating the zone that the paper web mechanical strength dies down; (II) Cha filtration character; (III) poor and variable pattern limits.
And, use " bulge " that spendable fibre morphology is restricted, this is because the paper of silk screen design is peeled off character.Also having a shortcoming is paper " personalization " scope very limited (for example having special little mark or other trade mark).
BP No 2286159 discloses and a kind ofly has been used for the thin paper method for printing that infusion beverage product filter bag such as tea bag process are used in production.But the document also discloses a kind of method that forms pattern in process of production or the little elephant of marking on a map of appropriateness is provided in thin paper, the zone that it can be upset Fiber Distribution and produce high fibre density and low fibre density.Although show that by optical contrast pattern is desirable with respect to the content that color in the bag is darker, there is a problem, promptly low fibre density areas subsequently causes paper strength significantly to descend.Also having a problem is possible cause losing of composition particle owing to the existence of these contrast district internal pores.The other method of using in the prior art relate to use hot calendering on thin paper, implements to heat and the synergy of pressure with conpressed fibers and reduce thickness.But, still there is identical problem, because the operation of heating and compression paper will inevitably upset fibrous web, may cause the forfeiture of structural intergrity.
The object of the invention provides can print the paper web that forms packaging material then, and described packaging material are suitable for packing the independent sector of infusion beverage.The present invention manages to avoid using the nonessential additive that needs in the print product.Another purpose provides the printing packaging that can use safely, and it does not need to use the additive that seldom contains in the non-printing zone in these packings, thereby does not need the further registration approval of food control office.It is desirable to, this packing should be convenient to use immediately, also should store longer a period of time.Another target of the present invention provides a kind of beverage packaging, and it comprises paper web of the present invention and infusion product.Another target is that described beverage packaging comprises beverage independent sector such as coffee or the tea that single uses, and does not need to take apart this packing.Another target is that the packaging material and the beverage packaging itself of manufacturing beverage packaging is can be biodegradable at least to a certain extent, thereby the consumer uses and handles packing and generally waste water and environment are not caused injurious effects afterwards.
