Problems solved by technology

However, the method of gradually heating up in the final process is still not effective, and it is still prone to problems such as skewing, wrinkling, shifting, and even slipping of the heat shrinkable film label.

Embodiment 1

[0019] In this embodiment, the method for placing a heat-shrinkable film label on the conical cup includes the following process steps:

[0020] A. First, print the graphic information with ink on the heat shrinkable film, which can print information such as product descriptions, and can also print various exquisite patterns or advertising patterns;

[0021] B. After printing the graphic information, print the hot-melt adhesive, cover the graphic information, and make a heat-shrinkable film label substrate; the heat-shrinkable film corresponds to the hot-melt adhesive coating at the mouth of the conical cup The amount is 1.5 times the amount of hot melt adhesive applied at other positions of the conical cup, and the curing temperature of the hot melt adhesive used is below 70°C, so as to facilitate the crosslinking and curing of the hot melt adhesive in the subsequent process;

[0022] C. Make the obtained heat-shrinkable film label base sheet into a heat-shrinkable film label...

Embodiment 2

[0027] In this embodiment, the method for placing a heat-shrinkable film label on the conical cup includes the following process steps:

[0028] A. First, print the graphic information with ink on the heat shrinkable film, which can print information such as product descriptions, and can also print various exquisite patterns or advertising patterns;

[0029] B. After printing the graphic information, print the hot-melt adhesive, cover the graphic information, and make a heat-shrinkable film label substrate; the heat-shrinkable film corresponds to the hot-melt adhesive coating at the mouth of the conical cup The amount is twice the amount of hot melt adhesive applied in other positions of the conical cup, and the curing temperature of the hot melt adhesive used is below 70°C, so as to facilitate the crosslinking and curing of the hot melt adhesive in the subsequent process;

[0030] C. Make the obtained heat-shrinkable film label base sheet into a heat-shrinkable film label acc...

Embodiment 3

[0035] In this embodiment, the method for placing a heat-shrinkable film label on the conical cup includes the following process steps:

[0036] A. First, print the graphic information with ink on the heat shrinkable film, which can print information such as product descriptions, and can also print various exquisite patterns or advertising patterns;

[0037] B. After printing the graphic information, print the hot-melt adhesive, cover the graphic information, and make a heat-shrinkable film label substrate; the heat-shrinkable film corresponds to the hot-melt adhesive coating at the mouth of the conical cup The amount is 3 times the amount of hot melt adhesive applied in other positions of the conical cup, and the curing temperature of the hot melt adhesive used is below 70°C, so as to facilitate the crosslinking and curing of the hot melt adhesive in the subsequent process;

[0038] C. Make the obtained heat-shrinkable film label base sheet into a heat-shrinkable film label a...

Abstract

The invention relates to a method for sheathing a thermal shrink film label to a cone cup, which comprises the following steps of: printing image and text information; printing hot melt glue; manufacturing a thermal shrink film label; sheathing the thermal shrink film label; and heating the cone cup to adhere the thermal shrink film label in three stages of steam heating, wherein a steam vent at the rim of the cone cup is heated for 8-12 s at the temperature of 80-90 DEG C in the first stage of steam heating, the steam vent at the middle cup body of the cone cup is heated for 8-12 s at the temperature 70-80 DEG C and the steam vent at the bottom cup body of the cone cup is heated for 8-12 s at the temperature of 70-80 DEG C. By using the method, the thermal shrink film label is smoothly and tightly attached to the surface of the cone cup and can be fixed to the largest diameter position of the rim of the cone cup, and the thermal shrink film label can not slip off the surface of the cone cup and is especially applicable to the Styrofoam cone cup with smooth surface; by printing the image and text information on the thermal shrink film, the image and text information can be prevented from wearing, but also the surface decoration effect of the cone cup is increased.

Description

technical field [0001] The invention belongs to the technical field of shrink film labels, and in particular relates to a method for nesting a heat shrinkable film label on a conical cup. Background technique [0002] Most of the existing beverage cups are disposable cups with smooth surface. Due to the smooth surface of the cup body, it is impossible to directly print exquisite patterns on the cup body, which limits its application. For example, Styrofoam (styrofoam) cups have unique advantages such as low cost and heat preservation, but due to their smooth surface and lack of exquisite packaging, they cannot be widely used in the vast beverage market. Later, a method of nesting a heat-shrinkable film label with exquisite patterns on the cup body appeared to improve the aesthetics of the beverage cup. [0003] However, the effect of this heat shrinkable film label on a cylindrical beverage cup is acceptable, but if the beverage cup has a certain taper, it is easy to cause ...
