Heat shrinkable film label printing process should pay attention to matters

Shrink film label printing method and other materials in general is the same, the difference is in the drying, layout, impact, ink, powder, solvents, storage, etc., should pay attention to.

Drying: the film is heated on the shrinkage, but because the raw material after drying apparatus for a short time, but will not affect the general, the shutdown should be open dryer immediately cut off the power supply. Conditional manufacturers can weaken the heat, strengthen the cold air device. Printing should be dry when rewinding.

Layout: shrink film sealing and bonding to trademark, in the plate should be considered when the joint part pattern broaden 2.4mm, to prevent the two to appear crack, affect the appearance.

Impact: PVC heat shrinkable film raw material factory has been corona treatment, printing without further impact, otherwise it will affect printing.

The best use of ink: ink special heat shrinkable film the film printing, OPP can also be used in printing ink or polyamide adhesive plastic gravure ink.

Solvents: benzene, esters can be, alcohol unfit.

Powder: if polyamide plastic ink printing. In the receiving or bonding machine should be added powder grinding device (talcum powder can be, gypsum powder should not) to prevent ink inner adhesion, adhesion. Such as greater humidity should pay attention to air. Such as the use of shrink film special ink does not have to add powder.

Raw materials: if the film thickness is Mujun, appears when the printing roller is fixed slide one or two.

Raw material storage: avoid contact with heat sources, chemical solvents and needle like solids in transportation and storage. Storage room must be kept cool ventilated, dry. Storage period should not exceed half a year.
