Embodiment Construction

[0012] A gasshang glue for PETG heat-shrinkable film suitable for high-speed pinhole glue spraying system. Gassho glue is made by mixing the following components: 1,4-dioxane, 1,3-dioxane, acetic acid Ethyl ester; the volume ratio of each component when mixed is: 1,4-dioxane accounts for 55%, 1,3-dioxane accounts for 35%, and ethyl acetate accounts for 10%;

[0013] The running speed of the high-speed palm-joining machine is: 300-450m / min;

[0014] The lateral shrinkage rate of PETG heat shrinkable film is: 55%-65%.

[0015] The specific implementation process is to take 55 liters of 1,4-dioxane, 35 liters of 1,3-dioxane, and 10 liters of ethyl acetate, mix the three materials well to form glue, and supply them to the palm machine;

[0016] When the palm-joining machine is working, the glue is evenly coated on the palm-joint surface of the PETG heat-shrinkable film material, and then the dissolved polymers are combined with each other through the pressure of the pressure roll...

Abstract

The invention discloses a PETG thermal shrinkage film gassho glue suitable for high speed gassho machines. The PETG thermal shrinkage film gassho glue suitable for high speed gassho machines is prepared from, by volume, 52 to 58% of 1,4-dioxane, 32 to 38% of 1,3-Dioxolane, and 8 to 12% of ethyl acetate through mixing. The operation speed of the high speed gassho machines is controlled to be 300 to450m/min; the transverse shrinkage rate of the PETG thermal shrinkage film is 55 to 65%; mixng is convenient; gassho effect is obvious; and gassho technology quality can be ensured.

Description

technical field [0001] The invention relates to the technical field of film label processing, in particular to a PETG heat-shrinkable film palm-joint glue suitable for a high-speed pinhole glue spraying system type palm-joint machine. Background technique [0002] Before the film label is attached to the bottle body, the two ends of the film label (gassing surface) need to be butted and glued together. This process is called gasshang; the common gasshang process is to apply glue evenly on the gasshang surface through a gassing machine, and then apply The process of synthesizing a cylindrical tube material from a sheet-shaped single-layer heat-shrinkable film. [0003] As a film label, PETG heat shrinkable film material has the characteristics of non-toxic, odorless, high strength, high heat shrinkage rate, and beautiful packaging effect. PETG heat shrinkable film has passed the US FDA's food contact standards. It can be used in food and personal health care product packagin...
