Packaging box product display field, which belongs to the most popular shrink film, can be applied in a variety of fields, shrink film as a plastic material, can be heated in the object around the tight contraction adhesion. Its application generally involves food packaging and so on. Of course, we are more concerned about whether the shrink film can be printed on both sides, we in this article will introduce the characteristics of shrink film printing, as well as some of the relevant technical considerations.
First of all, we need to first understand what is shrink film, and the working principle of shrink film, it is made of polyolefin, PVC or polyethylene and other materials, whenever heated, the film will shrink, so that it closely fits the shape of the product covered, which not only provides a secure seal, but also enhances the visual appeal of the product and improves brand awareness. The packaging industry will continue to evolve in the future and the wireless possibilities of shrink film printing will increase.
There are several ways to print on shrink film, including flexographic printing, digital printing and screen printing. Each technique has its advantages and limitations, especially when printing on both sides of the film:
Flexographic printing, which uses a flexible letterpress plate to transfer ink to the top of the film, is generally designed for one-sided printing. Flexographic printing is effective for high-volume printing and produces high-quality images, but two-sided printing can be achieved by printing on both sides of the film, which increases production time and costs.
Digital printing has revolutionized the way products are printed, with high quality images as well as designs printed directly onto the film, particularly suited to small runs and bespoke designs, digital printing can be done on both sides of the shrink film but careful consideration needs to be given to the inks used and the drying process to ensure that prints don't smudge or bleed through.
Screen printing, suitable for both small and large scale production, involves pushing ink through a mesh screen onto the film. Screen printing can produce vibrant colors, however, as with flexo printing, it is usually more efficient to print on one side, and to print on both sides requires turning the film over and reprinting it, which is labor intensive.

While it is technically possible to print on both sides of shrink film, there are several factors to consider:
-Ink compatibility: the type of ink is very important, all inks are not the same in terms of their characteristics, some inks may require a specific curing process, so the type of ink is crucial, it is wise to choose an ink that is compatible with the film material
-Design Layout: Considering the design layout, the pattern presented to the operator should be clearly visible, in addition, its alignment must also be clearly visible, misalignment will cause poor printing results.
Production costs: In terms of cost, double-sided shrink film is bound to be a bit more than single-sided shrink film, because it requires additional printing steps and may also require specialized equipment, for companies that need this, must weigh the double-sided printing.
-Applications and uses: If double-sided printing is attached to the surface of the product, both sides can be displayed, enhancing the overall display effect, then double-sided printing has an advantage, on the contrary, if only one side of the display, then the choice of single-sided printing is more favorable. So the choice of single-sided printing or double-sided printing needs to be based on the company's needs!
In summary, although double-sided printing on shrink plastic has gradually become popular, but we need to carefully plan the operation, using the correct printing technology and consider a variety of factors, If you have any needs for printing shrink film, please feel free to contact our company. Hoping that the company has a need for double-sided shrink film can be clear about their positioning needs, budget, printing equipment capacity. Double-sided printing on shrink film can enhance the product display, attractiveness and brand awareness.
