Comparison Between In-Mold Labels and Traditional Printing Methods

In-mold labeling is a modern decoration technology in plastic injection molding

In-mold labeling is a modern decoration technology in plastic injection molding and is rapidly gaining popularity. In-mold labeling is a high-quality decoration method, which is increasingly popular when the goal is to provide excellent appearance and maximum design freedom for the final product, such as IML butter container, IML margarine container, IML spread container, IML ice cream container or IML yogurt cup. In-mold labeling is not only attractive in packaging, but also in terms of environmental protection. For both non-recyclable and recyclable packaging, the in-mold labeling tags are made of the same material as the container. For die-cutting experts, in-mold labeling has been a constantly evolving topic for more than 20 years. Especially for the die-cutting of in-mold labeling tags, it is obvious that new innovative technology must be adopted to meet the constantly changing in-mold labeling market and the growing customer demand.

Comparison between in-mold labeling and traditional printing methods for empty margarine tubs

In-mold labeling is an injection molding process that uses labels to decorate plastic parts during plastic injection molding. In short, pre-printed labels are automatically inserted into the cavity of the injection mold, and the plastic is injected onto the label. This produces a plastic part with a "labeled" label that is permanently fused to the part itself.

The in-mold labeling market continues to experience rapid growth and adoption in various end markets. These markets include many high-volume consumer applications, such as food packaging, industrial containers, household goods, candy, and personal care products.

Compared to using adhesive labels or traditional printing methods, using in-mold labeling for empty margarine tubs has many technical and commercial advantages. These include but are not limited to: plastic parts with visual appeal; greater flexibility in part design of empty margarine tubs compared to traditional printed products; environmentally friendly packaging, with single plastic material that is recyclable; non-circular packaging has higher spatial efficiency than circular packaging; a single process for injection molding and decoration of empty margarine tubs, eliminates secondary processes and staged inventory requirements; batch production runs, eliminates set-up waste in printing; stackable to save space and transportation costs, among other benefits.

In-mold labeling container products have quickly expanded into new market applications, including for disposable cups and household cleaners, ice cream, paints and coatings, personal care, yogurt, prepared meals, condiments, and empty margarine tubs.
