Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1 to Figure 2, a kind of grid location analyzes the method for shrink film deformation, and it is made up of following steps:
A. some equal-sized grids 2 are evenly set at heat shrink films, obtained grid heat shrink films 1;
B. the obtained grid heat shrink films 1 pair of product to be packaged 3 of step a is utilized to carry out heat shrinkable package;
C. the grid deformation size of the grid heat shrink films 1 after shrink wrapping is measured, and calculate the deformation of zones of different.
Wherein, described step a is specially: planning grid pattern, and according to the lattice pattern-making forme designed, utilizes described pattern forming to carry out printing operation to heat shrink films, obtained grid heat shrink films 1.
Concrete, heat shrinkable package simulation actual production packaging process of the present invention carries out, design sketch after packaging as shown in Figure 2, measured by the deformation size of the grid 2 to zones of different in Fig. 2, the undeformed region 4 of grid heat shrink films 1 can be marked off, deformation is zonule 5 comparatively, deformation is large regions 6 comparatively, for the design of heat shrink films 1 provides foundation, make designer can learn deformation position and the deformation degree of heat shrink films 1 in advance, thus rationally avoid deformation comparatively large regions 6 in design process, effectively utilize undeformed region 4 and deformation comparatively zonule 5, solve the random distortion of heat shrink films and have a strong impact on the problem of design effect, substantially increase design efficiency and the result of use of the packaging pattern of heat shrink films.
