The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 2, a kind of grid location is analyzed the method for shrink film deformation, and it is comprised of following steps:
A. at heat shrink films, some equal-sized grids 2 are set evenly, make grid heat shrink films 1;
B. utilize 1 pair of product to be packaged of grid heat shrink films 3 that step a makes to carry out heat shrinkable package;
C. the grid deformation size of the grid heat shrink films 1 after shrink wrapping is measured, and calculated the deformation of zones of different.
Wherein, described step a is specially: the planning grid pattern, and, according to the lattice pattern-making forme that designs, utilize described pattern forming to carry out printing operation to heat shrink films, make grid heat shrink films 1.
concrete, heat shrinkable package simulation actual production packaging process of the present invention carries out, design sketch after packing as shown in Figure 2, deformation size by the grid 2 to zones of different in Fig. 2 is measured, can mark off the undeformed zone 4 of grid heat shrink films 1, deformation is than zonule 5, deformation larger regional 6, for the design of heat shrink films 1 provides foundation, make the designer can learn in advance deformation position and the deformation degree of heat shrink films 1, thereby in design process, rationally avoid deformation larger regional 6, effectively utilize undeformed zone 4 and deformation than zonule 5, solved the random distortion of heat shrink films and had a strong impact on the problem of design effect, design efficiency and the result of use of the packaging pattern of heat shrink films have greatly been improved.
Wherein, lattice in described step a is square net 2, each sub-box shape on described grid 2 is identical, equal and opposite in direction, described grid 2 adopts the square sub-box of standard, is convenient to distinguish intuitively deformation larger regional 6 and the undeformed zone 4 of grid heat shrink films 1, can first by visual inspection, distinguish the zones of different of grid heat shrink films 1, and then carry out the measurement of size for different zones, practical.
Wherein, the length of side of described square net 2 is 10mm, is convenient to observe, and conveniently carries out dimensional measurement.
Wherein, described step b is specially: utilize the grid heat shrink films that step a makes to pack in advance product to be packaged, product after packing is sent into the shrink oven passage carry out heat shrinkable package, described heat shrinkable package simulation actual production packaging process carries out, can react really contraction state and the shrinkage degree of grid heat shrink films 1 in the heat shrinkable package process, accuracy is high as a result.
Wherein, distortion of the mesh size to the grid heat shrink films in described step c is measured, comprise stretched dimension, shrinkage rule little progress row are measured, the size of carrying out the grid 2 of the grid heat shrink films 1 after heat shrinkable package becomes large or diminishes, larger impact is caused to the pattern that is printed on grid heat shrink films 1 in capital, therefore, stretched dimension, shrinkage rule little progress row to grid 2 are measured, the undeformed zone 4, deformation that can guarantee accurately comprehensively to mark off grid heat shrink films 1 is larger regional 6 than zonule 5, deformation, and result is accurate.
As shown in Figure 3, design a kind of thermal contraction packaging film of PET bottled drink for packing 550ML, 24 bottles of individual packaging accommodation bottle dixie cups, body diameter 64mm, bottle height 227mm, after overheat contraction, dimensional measurement, deformation region mark as shown in Figure 3.
Concrete, the zone definitions that the size of grid 2 after measuring is not changed is undeformed zone 4, and mark is carried out in such zone, for follow-up design and printing work provide foundation.For example,, for being out of shape after the regions contract of avoiding being printed with bar code, cause the bar code None-identified, the bar code design should be positioned over undeformed zone 4 and be optimal selection; The GB look of food security QS sign is Pantone300, and border width is unified is 0.5mm, in order to prevent the QS sign after heat shrinkable package, deformation occurs, and the design of QS sign is positioned over undeformed regional 4 is optimal selection.
Wherein, the zone definitions that each monolateral change in size of grid 2 after measuring is less than or equal to 2mm is that deformation is than zonule 5, and mark is carried out in such zone, for follow-up design and printing work provide foundation, this zone is the suggested patterns design section, and suggestion is positioned over this position with important pattern (comprising LOGO, emphasis advertisement information etc.).
Wherein, be deformation larger regional 6 with each monolateral change in size of grid 2 after measuring greater than the zone definitions of 2mm, and mark is carried out in such zone, for follow-up design and printing work provide foundation, can design large color lump in such zone and set off figure, play certain decoration function.
Unaccounted technical characterictic in the present embodiment, adopt the explanation in embodiment 1, at this, no longer repeats.
Above embodiment only is used for technical scheme of the present invention being described but not limiting the scope of the invention; although with reference to preferred embodiment, the present invention is explained in detail; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement technical scheme of the present invention, and not break away from essence and the scope of technical solution of the present invention.
