Why Conventional Seals Peel Off in Freezers
In fact, conventional seals cannot be used in subzero temperatures. Their materials and adhesives are not designed for low temperatures, causing the adhesive to freeze or become weakened by condensation, leading to peeling. Additionally, if printed individually, the ink may smear, making it unreadable.
If you plan to use seals in subzero conditions, it is crucial to select materials and adhesives that are suitable for freezer environments. When producing seals, choose the ones that best match your intended conditions.
Three Key Features of Freezer Seals That Don’t Peel
The characteristics of freezer seals that don’t peel are as follows:
- Selection of materials suitable for freezing
- Use of adhesives designed for freezer conditions
- Resistance to moisture
Feature 1: Selection of Materials Suitable for Freezing
When producing freezer seals, it is necessary to choose materials that are appropriate for the environment in which they will be used. A moisture-resistant film material is recommended, and it is common to use Yupo, which is cost-effective and highly durable.
If you would like to learn more about Yupo, please refer to the article below.
Yupo is a film material that, despite its affordability, boasts high durability.
Freezers tend to cause condensation, making seals prone to moisture, so untreated paper materials are not suitable. Although lamination can enhance strength and water resistance, it cannot completely prevent moisture from seeping into the adhesive surface.
In addition, among paper materials, only mirror-coated paper is available for freezer use. While it is less durable compared to Yupo, it is more affordable and is mainly used for frozen foods.
If you would like to know more about mirror-coated paper, please refer to the article below.
Mirror-coated paper is a glossy paper material that exudes a shiny finish.
In the first place, although traditional Japanese paper or craft paper have attractive textures, they are not suitable for lamination. If you are unsure about the suitability of a material, feel free to contact the printing company you are considering for your order.
The characteristics of each material and details about lamination processing are explained in detail in the article below.
Feature 2: Use of Adhesives Designed for Freezer Seals
Conventional adhesives are vulnerable to low temperatures and tend to peel off when placed in a freezer, so specialized adhesives are typically used for freezer seals.
In fact, the need for specialized adhesives is not limited to freezer seals. In the temperature range of refrigerators (15–5℃), the adhesive strength of seals can also decrease, so there are adhesives designed for refrigerated conditions as well.
It is important to use the optimal adhesive for freezer or refrigeration conditions based on the temperature range of the storage environment. If you are uncertain, consult with your printing company to produce functional seals tailored to your needs.
Feature 3: Resistant to Moisture
The adhesive used for freezer seals is not only designed to withstand low temperatures, but it is also resistant to moisture. In freezers, condensation can occur, and without water resistance, the seal may become soggy or deteriorate.
Therefore, freezer seals are highly valued for use on frozen foods that are frequently accessed and on seafood products that are prone to moisture exposure.
Our company produces not only freezer seals but also various other types, such as strong adhesive versions that are difficult to peel off and re-peelable versions that can be repositioned. If you wish to create custom-made seals tailored to your needs, please contact us.
Three Important Considerations When Producing Freezer Seals That Don’t Peel
The key points to consider when producing freezer seals that don’t peel are as follows:
- The optimal adhesive varies depending on the timing of application
- Ease of application is also influenced by the material and shape of the surface where it is applied
- Be aware of the duration for which the seal needs to remain attached
Consideration 1: The Optimal Adhesive Varies Depending on When the Seal Is Applied
For freezer seals, apply them when the product is dry at room temperature. If the seal is applied while wet due to condensation, the adhesive will not perform properly, and the seal may peel off because of the moisture between the product and the seal.
It is quite common for the environment where the seal is applied to differ from the storage environment. When creating freezer seals, be sure to communicate as many details as possible to the printing company so they can recommend the most suitable adhesive for your product.
Consideration 2: Ease of Application Depends on the Material and Shape of the Surface
The tendency of a seal to peel off is influenced not only by its adhesive strength but also by the material and shape of the surface where it is applied. Areas that are wet due to condensation or have an uneven surface are not suitable for applying seals.
If the application surface has factors that make peeling likely, be sure to consult with the printing company in advance. As an aside, a common cause of seal peeling is insufficient pressure during application. Make sure to firmly press the seal when applying it.

Consideration 3: Be Aware of the Duration the Seal Needs to Stay Attached
For labels applied to products such as frozen foods, it is crucial that the seal remains intact and legible throughout the entire shelf life of the product.
However, for those unfamiliar with seals, considering the duration for which a seal must remain adhered can be challenging. If you are in doubt, do not hesitate to consult with a reputable printing company.
Our company produces a wide variety of seals, ranging from standard types to freezer types. If you have any questions regarding seal production, please feel free to contact us.
Applications Where Freezer Seals That Don’t Peel Are Effective
The main applications where freezer seals are effective are as follows:
- Packaging decoration for frozen products
- Labels indicating expiration dates and ingredients on frozen foods
Application 1: Packaging Decoration for Frozen Products
The labels used on frozen products are freezer seals. The range of products sold frozen is vast, including ice cream, frozen fish and meat, and ready-to-eat meals.
These include both affordable options suitable for everyday use and high-end products that are typically reserved for special occasions. Because many products are similar, differentiating your own product from the competition is essential for successful sales.
When used as packaging decoration, freezer seals add value to the product’s appearance and capture the interest of customers. If you have such needs, consult with a seal printing company.
Application 2: Expiration Date and Ingredient Labels on Frozen Foods
Freezer seals are also used as food labeling for indicating the expiration dates and ingredients of frozen foods. Since the content of food labels is strictly regulated by law, it is the seller's obligation to comply with these guidelines.
If you produce labels for frozen foods using a household printer, there is a risk that the text may smudge and become unreadable, or the seal itself may peel off during storage. This would prevent consumers from obtaining the necessary information for safety and peace of mind. It is crucial to use freezer seals on frozen food labels to ensure consumers can use these products with confidence.
Case Studies of Freezer Seal Production
Our company produces not only freezer seals but also refrigerated seals. Please take a look for reference.
Because refrigerated and frozen products are stored at different temperature ranges, the type of adhesive used also differs. Moreover, the ability to adhere properly even to uneven surfaces is a characteristic unique to adhesives designed for products like ham.
We use Yupo 80μ as the material, which is excellent in terms of water resistance and durability.
Select the Appropriate Materials and Adhesives to Produce Freezer Seals That Don’t Peel
When conventional seals are used in low-temperature environments, the adhesive strength can diminish, leading to peeling. Additionally, some materials may allow condensation to smear the printed content, making it difficult to read. Therefore, when producing seals for freezer environments, it is necessary to choose materials and adhesives that are appropriate for those conditions.
Our company is a printing firm that produces custom-made seals designed to add value to your products.
