Abstract
The invention relates to a stretchable paper product. The invention provides a paper material. The paper material comprises one layer or more layers, wherein the paper material can be extended for at least 5% in a machine direction (MD) and can be extended for at least 5% in a cross direction (CD). The invention further provides a package formed by the paper material.
Description
Technical field
The product that the present invention relates to stretchable paper and formed by this stretchable paper.
Background technology
In a lot of fields, conventionally all wish petroleum-based plastics to replace with recyclable materials.In packaging field, be paper to conventional plastic alternative attracting people's attention especially.But traditional paper has many shortcomings when with plastics comparison.For example, common paper extensibility compared with being permitted eurypalynous plastics is quite little, and this has limited the degree of depth that can obtain in hot forming or vacuum forming machine.In addition, in extrusion process, for example, in the time that common paper is shaped as three-dimensional packing (pallet) in mould, paper produces fold, and this has caused ugly outward appearance.
Summary of the invention
A kind of paper wood is provided, and this paper wood comprises one or more layer, and wherein said paper wood is upper extensible at least 5% in machine direction (MD), and at horizontal direction (CD) upper extensible at least 5%.This paper wood makes it possible to form the three-dimensional body forming with plastics before.
The extensibility of described paper wood is all preferably at least 6% in MD and CD direction.For example, this extensibility can be all at least 7% on both direction.In one embodiment, this extensibility is at least 7% on CD, and on MD, is 14%.Described extensibility can for example be measured according to standard ISO 1924-3.
Described paper wood can comprise two or more extensible ply of papers that are for example bonded to each other.Described adhesive can be for example PE layer or water base viscose glue.Paper wood of the present disclosure thereby can be layered product.
Described paper wood can be coated with one or more coats with one or more barrier properties.Alternatively or as a supplement, can be by the film viscose glue with one or more barrier properties to paper sheets to form barrier layer.The example of barrier properties comprises grease block, gas barrier and moisture block.This barrier properties is for example attractive in the time of packaged food.
The grammes per square metre of described paper wood can be for example 50g/m
2to 600g/m
2.
Paper wood of the present disclosure makes it possible to form aestheticly attractingly to be had embossing and shows surperficial displaying articles.
In addition, paper wood of the present disclosure can be used to form three-dimensional packing.
For example, provide a kind of pallet, for example meal tray, this pallet comprises by the sidewall forming according to above-mentioned material and diapire.Should be understood that described pallet is formed by material described in monolithic.In one embodiment, this film is attached to the top edge of described sidewall, thereby forms enclosure space in described pallet.Food or other guide thing can be arranged in described enclosure space.
A kind of blister pack is also provided, and this blister pack comprises by the multiple cavitys that limit according to above-mentioned material.
A kind of clamshell package is also provided, and this clamshell package is by forming according to above-described paper wood.
A kind of packaging is also provided, and this packaging comprises the hypocrateriform that formed according to above-mentioned paper wood by monolithic or bowl-shape body and circumferential rim portion.Described body has the degree of depth and width, and described rim part is outwards outstanding from the top edge of described body.The described degree of depth is larger, and the meaning is that the ratio of the described degree of depth and described width is 1:8 at least.Preferably, the ratio of the described degree of depth and described width is 1:7 at least, such as at least 1:6,1:5,1:4,1:3 or 3:8.
Paper wood of the present disclosure makes it possible to form the rim part of substantially flat (corrugationless).
Described width is the beeline between the relative top edge of described body.This means at described body and have in the packaging of circular upper edge, described width is the diameter of top edge.Have in the packaging of rectangle top edge at body, described width is the distance between two long limits of top edge.
