OSAKA SEALING PRINTING CO., LTD. began selling "Cillpita," a label that can be attached to condensation-prone surfaces such as chilled products, in October 2022. Some companies that are already using "Cillpita" have reported a significant reduction in the number of labels that fall off before and after use, and it is a product that boasts high adhesive strength.

About "Cillpita"

This label can be attached to chilled products that are prone to condensation.
The product was originally created as a result of a consultation with a single company, but as the need for refrigerated products increased, attention was drawn to "Cillpita," and the decision was made to sell it to the general public.

Reports of label detachment have dropped dramatically since the introduction of "Cillpita"

When a product is moved from a chilled temperature range to a room temperature environment, the product's temperature rises and the air around the chilled product cools. The temperature difference between the product and the environment where it is attached causes condensation, and moisture often adheres to the product's surface.
The challenge was that labels could not be attached firmly to the product surface due to the effects of condensation and poor adhesion at low temperatures, causing many of the labels to slip off during work. However, by developing and selling labels that have stable adhesion even on surfaces with condensation or other water droplets, we have received positive feedback from the field, such as "the number of complaints about labels falling off has decreased significantly."

New adhesive technology developed by OSP

(1) Adhesive strength in chilled temperatures

Adhesive strength varies greatly depending on the conditions of use. At low temperatures, general adhesives become hard and lose their adhesive strength. Therefore, we developed an adhesive that utilizes new technology that makes it easier to maintain flexibility even at refrigerated temperatures, allowing it to maintain its adhesive strength.

(2) Adhesive strength when attached to a condensation surface

When a product is moved from a chilled temperature range to a room temperature environment, the product temperature rises, the air at the interface cools, condensation occurs, and moisture often adheres to the surface. When using paper base materials or cast-coated tack paper used in other stickers and labels as the surface paper, there were issues with the paper becoming soggy due to the effects of condensation, or the edges curling back toward the surface, causing peeling forces.

Therefore, we reviewed the surface paper material and used synthetic paper that is highly water-resistant and less affected by condensation, reducing the tendency for the paper to peel off on condensation surfaces. We also tested and compared it with existing adhesives and used an adhesive that achieved higher adhesive strength, resulting in a product with stable adhesive performance even on water droplets. The emulsion-based adhesive used in the product is an environmentally friendly product developed independently by the OSP Group, which has developed a wide variety of stickers and labels.

*Adhesion test content: "Adhesion strength to condensation surface"
We created an environment where condensation would occur and measured the adhesive strength of Cillpita. The values are for a polyolefin wrap with condensation on its surface.

Development of “Labels that can be attached even when wet”

The birth of Cillpita was triggered by a consultation received from a company to our sales representative.
"Doubles of labels come off on chilled products every year. Is there anything we can do to improve this?" After hearing from the company, the sales representative who received the request determined that the existing labels handled by our company would be difficult to apply, and consulted the research and development department. From there, the sales and research and development departments formed a team and started a project to solve the company's problems. The spirit of "customer first" (※), which is the philosophy of the entire OSP Group, and which strives to meet customer requests to the greatest extent possible, led to the birth of a new product.

Our research department staff visited customers' sites numerous times to see with their own eyes the conditions under which the products were handled and the circumstances under which the labels were affixed. They then conducted experiments based on the information they gathered on-site, making repeated improvements and tests.

About three years after we received the inquiry from the company, we completed the first prototype of "Cillpita", a label that can be affixed to chilled products. We continued to make improvements after that, and succeeded in getting closer to the desired result, which has been well received.

(※)Customer first means:
This is the management philosophy that the OSP Group has held dear for the 95 years since its founding, and represents our desire and attitude to sincerely think about "what can I do for our customers" and to deliver good work with sincerity.

Products that meet the needs of the world

In recent years, the COVID-19 pandemic has expanded the ready-meal market, and the need for processed foods distributed at low temperatures is on the rise. As per capita expenditures on prepared foods, including chilled foods, continue to rise, and the amount of logistics through the cold chain has also increased, we have been receiving more and more inquiries every year about attaching labels to condensation surfaces. Originally, this product was produced exclusively for the company that inspired its development, but as demand grew, it was decided to sell it to the general public.
We aim to expand our sales channels nationwide so that we can contribute to reducing the problem of labels falling off at even more logistics sites in the future.
