Abstract
The forming method of new-type house-shaped packet is characterized by using composite material packaging paper to make box and including the procedures of pasting sealing strip, side edge butt jointing and sealing, pyramiding, preforming roof, bottom edge butt jointing and sealing and cornering, etc.. It is simple in production process, easy to operate and control, low in cost, good in barrier property and long in normal-temp. fresh-keeping period.
Description
The present invention relates to a kind of manufacturing process of beverage package box, the manufacturing process of particularly a kind of composite room shape bag.
In the prior art, room shape bag is to make with special paper, and good looking appearance is generous, liked by the consumer.But because the oxygen barrier of packing box, poor every optical property, room shape bag requires in that to be lower than 5 ℃ of following temperature fresh-keeping, freshness date just seven days.Seasoning conditional request height, freshness date is short, has seriously restricted the circulation of product and has disappeared and sold, packing box is special with the production technology and the prescription of paper, and quality requirement is very high, the production shaping complex procedures of packing box, apparatus expensive, packing cost are also higher, have increased consumer's burden.
The objective of the invention is to provide for the shortcoming that overcomes above-mentioned prior art a kind of manufacturing process of house-shaped bag, simplify production technology and equipment, reduce production costs, room temperature storage, transportation increase the normal-temperature fresh-keeping phase, promote products in circulation and sale.
Purpose of the present invention can realize by following measure: this packing box selects for use plastic-aluminum paper multi-layer compound package paper to make, and its manufacturing process is as follows:
Composite packaging paper one side is heated, along in this heating edge on card plastic sealing strip, another trimming is taken and is placed on card and has outside the sealing strip trimming, the heating pressurization is bonded and sealed, overlap joint growth tubular, plastic sealing strip is sealed the interior trimming of overlap joint, by the truncation of single box specification separately, single box inserts roll extrusion barring on mould, make box body present the tetragonal body shape of lower through-hole, roof shape mold pressing preform is pressed on cubic box top, cubic box bottom butt joint heating press seal, the base angle presses Zhe to return at the bottom of the box, bonding is positioned at the bottom of the box, form the tetragonal body of upper shed,, just become a room shape bag as long as cubic box top is sealed by preformed shape, joint strip in the room shape packet shaping process, lap seal, the butt joint back cover all is that heating is carried out, its heating-up temperature is 100-150 ℃, barring, the roof preform, the Zhe base angle all is to adopt the equipment of prior art to carry out, and corresponding more mold exchange is finished.
Embodiments of the invention are provided by following: this room shape bag adopts compound package material to make, compound package material is five layers of composite packaging paper, be plastic layer, paperboard layer, plastic layer, aluminium platinum layer, plastic layer, it has good in light, oxygen barrier and forming property, to the drink of packing can storage at normal temperature, transportation, freshness date be all more than some months.Composite packaging paper is by mechanical transmission, and to the heating of one side, heating-up temperature is 128 ℃ by hot blast, sticks plastic sealing strip to roll extrusion in the heating trimming, and the sealing bar is the PP bar, the inner plastic of wrapping paper and PP strip hot melt bonding.The outside that is placed on the sealing strip limit is taken on another packing trimming, being heated to 128 ℃ of roll extrusion by hot blast is bonded and sealed, the Cheng Yichang tubular, sealing strip is sealed the trimming in cylindrical shell, make not oxidation of trimming, non-leakage, by the truncation of single box specification standards separately, insert mechanical stitch barring on the square mould, make single box become to go up the tetragonal body of lower through-hole, again roof shape mold pressing preform is pressed on cubic box top, press CREASE MARK, the butt joint heating pressurization of box bottom, four directions is bonded and sealed, heating-up temperature is 128 ℃, and cubic box base pressure is flat, and base angle Zhe at the bottom of box returns, at the bottom of being bonded and fixed at box by viscose glue, room shape packet shaping is finished.During application, after the can drink, after the heat-sealing of box top, become room shape bag.
Technical process of the present invention is simple, and the equipment that operation control room shape easy, that produce is wrapped is simple, cheap.The room shape bag oxygen barrier, good that this method is produced every optical property, packaged products qualification rate height, the normal-temperature fresh-keeping phase is long, can promote the circulation sale of product, adapts to consumers in general's needs.
Claims (2)
1. the manufacturing process of a house-shaped bag, it is characterized in that composite packaging paper one side heating, along in this heating edge on card plastic sealing strip, another trimming is taken and is placed on card and has outside the sealing strip trimming, the heating pressurization is bonded and sealed, sealing strip is sealed the interior trimming of overlap joint, and by the truncation of single box specification separately, single box inserts that the roll extrusion barring becomes the cubic bodily form on mould, roof shape mold pressing preform is pressed on cubic box top, butt joint heating press seal at the bottom of the box of four directions, the base angle presses Zhe to return at the bottom of the box, and bonding is positioned at the bottom of the box.
2. method according to claim 1 is characterized in that obedient sealing strip, lap seal, and the heating-up temperature of Butt sealing is 100-150 ℃.
