The process is divided into the following three steps: the first step, preparation of points to compensate for textured test containers; the second step, preparation of points for forming color printing film gravure plate printing roller; the third step, color printing film fixed-point polypropylene plastic containers Manufacturing. The color printing film fixed-point forming polypropylene plastic container manufactured by the process has the characteristics of beautiful appearance, low manufacturing cost, sufficient information on the packaging, richness, no printing ink shedding, no stacking of containers and the like, and is an ideal convenience food. Acrylic packaging containers. Sovereignty item 1. A color printing film fixed-point forming process for polypropylene plastic containers, which is characterized in that: the process is completed in the following steps: Step 1 : Preparation point compensation Mesh test container First design Fixed point compensation Mesh version The manuscript [3], the size of the figure is based on the horizontal axis of the mouth of the container [1], increase the size of 5 ~ 10mm, fixed-point compensation mesh pattern manuscript [3] The center of the pattern is set to 5 ~ 15mm The positioning mark [5] uses the center of the positioning mark [5] as the shaft diameter difference to be the concentric pattern of the positioning mark [5] axis length until it covers the entire pattern, and then uses the center of the positioning mark [5] as the center Line grid, vertical and horizontal line spacing of 0.5 ~ 1.5mm; according to the fixed point compensation mesh pattern manuscript [3] made of fixed point gravure gravure plate printing roller; polypropylene film using the above-mentioned fixed point offset gravure plate printing roller The gravure printing is performed to make a fixed-point compensating moire test film; the film is heat-sealed with a polypropylene sheet to form a fixed-point compensating moire test sheet; the fixed-point compensated moire test sheet is used to mark the center of the reticulate pattern [5 ] Corresponding position of the corresponding mold center and net position corresponding to the position Point thermoforming or suction molding, made of fixed-point compensation mesh test containers [7]; the second step, prepare points for the formation of color printing film gravure plate printing roller according to the fixed point compensation mesh pattern test container [7] of the deformation of the pattern Determine the design scope of the container body pattern, design the container body pattern [10] within this range, divide the block according to the design of the container body pattern [10], and then draw each block on the surface of the fixed point compensation mesh test container [7] Contour [11], according to the position of the fixed-point compensation mesh test container [7] where the contour line [11] is located, corresponds to the fixed point compensation mesh pattern [3] the position of the corresponding mesh lines, determine the container body pattern [10] deformation compensation plane contour line [12], the pattern corresponding to each block contour line [11] is uniformly deformed so that it completely coincides with the container body pattern [10] deformation compensation plane contour line [12], in the plane After the pattern [13] is centered with a positioning mark [14] with a shaft diameter of 5 to 15 mm, a spot-printed color printing film gravure plate printing roll can be prepared. In the third step, the production of a color printing film fixed-point molding polypropylene plastic container is adopted. Two-step preparation of spot forming color printing film gravure plate printing roller The polypropylene film is printed in the gravure and printed on it to make a color printing film [2]. The color printing film [2] is heat-sealed with a polypropylene sheet to form a fixed-point color printing composite sheet. The flat pattern center is formed by the fixed-point color printing composite sheet. The positioning mark [14] corresponds to the center position of the mold, the position of the plane pattern corresponding to the position of the corresponding position of the mold, and carries out fixed-point thermoforming or suction molding. After finishing and packaging, it is a finished product of a color printing laminated polypropylene plastic container.
