Abstract
The invention discloses a waterproof packaging bag. The waterproof packaging bag comprises a substrate and a paper layer and further comprises a partition plate, wherein an environment-friendly water-based adhesive composite film is fixed to the paper layer, a glitter powder layer is combined with the outer surface of the film, the paper layer and the film are fixedly connected through an adhesive layer, the adhesive layer is made of polyurethane adhesive, and the partition plate is arranged on the paper layer so as to divide a carton formed by the paper layer into two cavities.
Description
Technical field
The present invention relates to a kind of packaging bag, particularly a kind of watertight packing bag.
Background technology
Packaging bag is also accustomed to being called handbag, be widely used in such as food, dress ornament, medicine, books and periodicals, the packing of product and process product etc., known packaging bag mainly by art paper and art post paperboard (White Card Paper) as substrate layer, on substrate layer and under use state, the surface of a side outward sticks with glue the compound one deck polyvinyl chloride film of agent (PVC film) again, polypropylene film (OPP film), pet film (PET film) or bidirectional stretching polypropylene film (BOPP film), and after after cutting (conventionally adopting cross cutting), make finished product packing bag.The concept of aforesaid art post paperboard refers to that being suitable between paper and Board make the general name of the white ground paper of business card, card or picture album lining paper.
At present, with regard to common on the market conduct, food, dress ornament, medicine, books and periodicals data, gift, workmanship and daily living article etc. packaging bag ubiquity packing and that have portable functional is led to fraud below: the one, anti-steam penetrablility especially water-proofness is poor; The 2nd, lose environmental protection, because conventionally use with poisonous and harmful composition if the adhesion agent of benzene, toluene, methyl alcohol, formaldehyde, styrene, methylene chloride, carbon tetrachloride and ethylene diamine etc. is by compound to film and base material (copper sheet paper or paperboard); The 3rd, tensile strength is poor and cause durable wear-resistant shortcoming; The 4th, outward appearance visual effect is stiff, does not have concavo-convex stereovision, three-dimension effect and highly glittering gorgeous and brilliant texture, thereby cannot meet the requirement of the continuous pursuit of people to packing material surface aesthetic.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of watertight packing bag, and described watertight packing bag not only can waterproof, also comparatively environmental protection.
A kind of watertight packing bag, comprise substrate and paper layer, described watertight packing bag also comprises dividing plate, in described paper layer, be fixed with environment-friendly water-based adhesion agent laminated film, and, be connected mutually between described paper layer and film by adhesive layer in conjunction with flash of light lamella at the outside face of film, the material of described adhesive layer is polyurethane binder, described dividing plate is arranged in paper layer, being divided into two cavitys by the carton that described paper layer was formed.
Wherein, the thickness that described paper layer, adhesive layer and film three stack up is less than the thickness of described substrate, and the thickness of described paper layer and film is identical.
Wherein, in described paper layer, offer inspection door.
Wherein, described paper layer is that grammes per square metre is the art paper of 100g/m2.
Wherein, the thickness of described film is 1.5 μ m.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the first preferred embodiments of watertight packing bag of the present invention.
Fig. 2 is the cutaway view of watertight packing bag of the present invention.
The specific embodiment
Below in conjunction with drawings and embodiments, the present invention is described in detail.
Please refer to shown in Fig. 1 and Fig. 2, the preferred embodiments of a kind of watertight packing bag of the present invention comprises substrate 1, on described substrate 1, be fixed with paper layer 2, in described paper layer 2, offer inspection door 21, in described paper layer 2, be fixed with environment-friendly water-based adhesion agent laminated film 3 and at the outside face of film 3 in conjunction with flash of light lamella 5.Between described paper layer 2 and film 3, be connected mutually by adhesive layer 4, the material of described adhesive layer 4 is polyurethane binder.Described dividing plate 20 is arranged in paper layer 2, so that the carton being formed by described paper layer 2 is divided into two cavitys, is designated as the first cavity and the second cavity.
The thickness that described paper layer 2, adhesive layer 4 and film 3 threes stack up is less than the thickness of described substrate 1.Described paper layer 2 is identical with the thickness of film 3.
Next how description is made to above-mentioned watertight packing bag:
A) raw material is prepared, and chooses the art paper that grammes per square metre is 100g/m2 (being paper layer 2) and chooses the Biaxially oriented polypropylene that thickness is 1.5 μ m (BOPP) film 3;
B) produce a bag uncoated paper, first environment-friendly water-based adhesion agent is applied to by steps A as spraying with roller coat or in other similar mode) side surface of the art paper chosen, then by by steps A) the BOPP film 3 chosen is compound on the art paper that is coated with environment-friendly water-based adhesion agent, obtain a bag uncoated paper, environment-friendly water-based adhesion agent in this step is preferred, but not limited to and uses vinyl urethane emulsion, the main component of this kind of emulsion is polyvinyl alcohol (EVA), pH is 6.5-8.5, and 15-25S when viscosity is 25 ℃, vinyl urethane emulsion is also referred to as vinyl urethane adhesion agent, it can substitute urea-formaldehyde glue, stopping formaldehyde discharges, owing to not containing solvent in this emulsion, thereby solvent-freely volatilize to atmosphere, can not cause pollution to environment and the infringement of human body,
C) cut, according to the developed area of the size specification of packaging bag, with cutting machine will be by step B) the bag uncoated paper that obtains cuts, and obtains a bag sheet;
D) printing flash of light lamella, the ratio that is first 1: 6 by weight by diamante and UV ink mixes, obtain printing slurry, the mode that then adopts screen printing is printed onto by step C printing slurry) on the bag sheet that obtains, more precisely be printed onto the surface of BOPP film 3, forming thickness on the surface of BOPP film 3 is the flash of light lamella of 80 μ m, then introduce the solid machine of ultraviolet light light dry, baking temperature control is 90 ℃, the gait of march control of bag sheet is 8m/min, obtain having at the surface conjunction of BOPP film 3 the one-tenth bag base of (being printed with) flash of light lamella, diamante described in this step also claims paillette, gold plaque, silver strip or metal powder etc., color is radium-shine look, golden, silver color, red, blue, green, black, pearly-lustre look, any one in camouflage color and purple,
E) become bag, by by step D) the one-tenth bag base that obtains is put to mould cutting machine cross cutting, after cross cutting, for bag machinery bag, obtains watertight packing bag, mould cutting machine described in this step and Bag Making Machine are equipment comparatively common in prior art, do not repeat them here.
Above specific descriptions of the present invention are intended to illustrate the implementation of specific embodiments, can not be interpreted as it is limitation of the present invention, those skilled in the art are under instruction of the present invention, can on the embodiment basis of describing in detail, make various variants, within these variants all should be included in design of the present invention.The present invention's scope required for protection only will be stated and be limited by described right.
