Abstract
An organoleptic multilayer paperboard based packaging uses a molecular sieve powder to adsorb low molecular weight oxidation products formed during the extrusion coating process. Figure 1 shows a polyethylene layer (10), adjacent a paperboard layer (12), and a low density polyethylene layer that contains a molecular sieve powder (14).
Description
Background of invention
Absorbent, as molecular sieve (ecolites), clay, silica and diatomite are used for removing the low-molecular-weight oxidation product that generates in the process as polyolefinic extrusion coating and so on; Remove from exploitation as structure the catabolite off-taste and the foul smell of (with from the hexanal of lipid oxidation or from the sulfide of protein degradation); With the foul smell that removes removal ink and/or varnish, these foul smell can be transferred to matte from slide with roll or slab form when storing.
Cereal, production persons such as juice complain the aroma and flavor of polymer in the paperboard based gable top box.More particularly, this aroma and flavor is called as the taste of " plasticlike " smell.This gable top carton mostly has polyalkenyl product contact layer, as low density polyethylene (LDPE).Foul smell and stink have been identified from low-molecular-weight volatility oxidation product such as hexanal.
In addition, gas and the flavor that is produced by the food degraded that is contained in the box also is a problem.Lipid oxidation in the cereal causes the generation of hexanal, and it makes cereal have unique smell.
The 3rd, do not wish that from the generation of printed substrate the compound of smell also is considered to a problem.
At last, removing in the product is not that undesirable compound of producing of product degraded also is considered to a problem.Such example comprises the water that contains malodorous compounds or contains from the water of by-product compounds in packing or the purge process.
Some existing patent has been discussed zeolite molecular sieve has been introduced in the plastic material, the compound that causes smell that produces when making this quasi-plastic property material to remove.
U.S.Patent No.5750611 relates to the thermoplastic compounds that contains absorbent, and these absorbents can reduce odour nuisance and taste.
U.S.Patent No.5948846 relates to polyolefin-based compositions and makes the method for the shaping object of said composition.This patent description in the polyolefin of the fatty acid-based lubricant that contains 0.1-5 part weight, use the zeolite of 0.05-2 part weight, to improve the special sense of formed article and bottle cap.
U.S.Patent 5 436 282 relates to eliminating in plastic material and the zeolite and produces gas/flavor material.This patent description in the plastics of fusion, add the zeolite of 0.05-0.3% weight, to reduce the discharging that produces gas/flavor material in plastic water pipe and the bottle.
U.S.Patent No.5 834 079 relates to the zeolite in the packing fiber widely.
International publication (International Publication) 94/03534 relates to compound resin composition with absorption and by its packing film that makes.Discussed in low or medium density polyethylene or polypropylene and to have used the 0.5-20% zeolite, with the gas that generates in the maturation that is combined in fresh fruit and the decay process.
Neither one is described the paper substrate package conformation article and is more specifically disclosed extrusion coating as process technology in patent of having discussed and publication.
An object of the present invention is to produce a kind of paper substrate package conformation article that contains additional molecular sieve in the extrusion coating process, this molecular sieve can be caught the nonspecific low-molecular-weight organic matter in the zeolite structure, thereby causes the improvement of product smell.
Another object of the present invention is to disclose a kind of paper substrate package conformation article that is mixed with molecular sieve, and molecular sieve is removed the compound of hexanal and so on, thereby prolongs the shelf life of product.
A further object of the invention is to mix a kind of molecular sieve in the paper substrate package conformation article, and to remove undesirable printing ink smell, this printing ink smell influences the quality of package food.
Summary of the invention
With a kind of absorbent, be used for paperboard laminate as molecular sieve, in order that remove the compound of hexanal and so on, to prolong the shelf life of product.This absorbent is used for removing as polyolefin, as low density polyethylene (LDPE), and high density polyethylene (HDPE), linear in density polyethylene, metallocene, the low-molecular-weight oxidation product that produces in the process of extrusion coating of polypropylene etc. and so on.
This molecular sieve is introduced the paper substrate package conformation article during pushing.The amount that this molecular sieve powder is sneaked into the low density polyethylene layer of product contact is the 5000-10000ppm scope in structure.

Detailed description of the invention
A kind of carton package structure, it is by extrusion coating or co-extrusion pressure rubberizing and introduces and a kind ofly be used to cause that the molecular sieve of organoleptic removing produces.
In a preferred embodiment, with molecular sieve powder, for example Abscents 3000TM (UOP sells on commission) or SmellriteTM (UOP sells on commission) mix with twin screw extruder machine with polyolefin polymer such as low density polyethylene (LDPE).10%mastibatch and low density polyethylene (LDPE) done to mix and make respectively contain 1000ppm (0.1%), the casting film (1mil thickness) of 5000ppm (0.5%) and 1000ppm (1.0%) molecular sieve powder.As shown in following table 1, to compare with low density polyethylene (LDPE) contrast film, octanal, aldehyde C-9 and the capraldehyde of removing with above-mentioned three kinds of films has the efficient greater than 70%.
