PP Synthetic Paper Adhesive Sticker – Frozen Adhesive Type

In simple terms, it is a specialized adhesive label material made with PP synthetic paper as the base substrate and a specially formulated frozen adhesive layer. It is specifically designed for low-temperature and even ultra-low-temperature refrigeration and freezing environments. Below is a clearer breakdown from two aspects: core composition and core characteristics:

Core Composition

  1. Base Substrate: The core is PP synthetic paper, which is not made from natural plant fibers. Instead, it is produced by extruding and biaxially stretching polypropylene resin mixed with inorganic fillers such as calcium carbonate. This substrate inherently has properties like waterproofing, oil resistance, tear resistance, and dimensional stability. It also supports various printing methods including flexographic printing and screen printing, laying the foundation for label information display and physical protection.
  2. Adhesive Layer: Uses low-temperature dedicated frozen adhesive, mainly low-temperature permanent rubber-based hot-melt pressure-sensitive adhesive. Unlike the adhesive layer of ordinary self-adhesive labels, it undergoes special formula adjustments to maintain stable adhesion in low-temperature environments—without becoming brittle or losing adhesive strength due to extremely low temperatures. Additionally, such labels are usually paired with glassine release paper, which has good strength and is suitable for high-speed automatic labeling, die-cutting, and other processing needs.

Core Characteristics

  1. Combines the advantages of PP synthetic paper and cryogenic adhesive. It inherits the substrate’s properties of waterproofing, oil resistance, friction resistance, and tear resistance, while relying on the cryogenic adhesive to achieve stable adhesion in low-temperature environments. Even on packaging surfaces with slight frost, it maintains good initial adhesion and holding power.
  2. Has a wide applicable temperature range—some products can work normally between -55℃ and 40℃. It can easily meet the labeling needs of products such as frozen foods and low-temperature medical reagents. Moreover, the product information printed on the label is not prone to blurring or fading due to low temperatures and humidity.

PP Synthetic Paper Adhesive Sticker (Frozen Adhesive Type)

It is a label material suitable for low-temperature/frozen environments. Its core advantage lies in stable adhesion at low temperatures while retaining the basic properties of PP synthetic paper.

Core Features

  1. Strong Low-Temperature Adhesion: Adopts frozen-specific adhesive. In low and ultra-low temperature environments ranging from -40℃ to 0℃, it will not lose adhesion or become brittle due to extremely low temperatures. It can firmly adhere to the surfaces of frozen food packaging, cold chain containers, etc., and is not prone to detachment.
  2. Condensation Resistance and Moisture Proof: Facing condensation, moisture, and frost common in frozen environments, the adhesive layer is not easy to hydrolyze. The label will not warp or delaminate due to moisture, maintaining a fully attached state.
  3. Excellent Substrate Compatibility: The matched PP synthetic paper itself has waterproof, oil-resistant, and tear-resistant properties. Combined with frozen adhesive, it can withstand physical friction and impact during the freezing process, making it not easy to be damaged.
  4. Stable Printed Information: PP synthetic paper has good surface printing adaptability. Text and patterns will not fade or blur in low-temperature environments, ensuring clear retention of product information such as shelf life and specifications.
  5. Health and Safety Compliance: Both the adhesive layer and PP substrate are non-toxic and odorless, with strong chemical stability. They can directly contact frozen food and meet food packaging hygiene standards.
  6. Adaptability to Low-Temperature Processing: Supports conventional processing technologies such as die-cutting and web printing. During processing in low-temperature environments, problems such as substrate cracking and adhesive overflow are not easy to occur.
