Cold-Resistant Permanent Closure Tape is a pressure-sensitive sealing tape for permanent closure of HDPE bags and compatible PE films used in refrigerated storage, cold transport and temperature-controlled packaging. Its construction consists of a film carrier, pressure-sensitive adhesive and release liner. Tape width, adhesive width, liner extension, roll length and core size can be matched to the bag structure and application process.

Product Construction
Film Carrier
The film carrier provides dimensional support during coating, slitting and rewinding. A reference thickness of 20–60 μm supports different tape formats and bag constructions.
Pressure-Sensitive Adhesive
The adhesive layer provides bonding to compatible PE film surfaces. Adhesive selection is based on application temperature, film surface, adhesive area and required closure conditions.
Release Liner
The release liner protects the adhesive before application and allows controlled removal during sealing. Liner extension can be matched to the bag opening and application method.

Key Performance
Low-Temperature Bonding
Adhesive response varies with temperature. The tape construction is selected according to the film temperature during application and the temperature exposure after closure.
Permanent Closure
The adhesive forms a permanent closure after application to a compatible film surface. Bond development is influenced by contact pressure, temperature, dwell time and film condition.
PE Film Compatibility
The tape is intended for HDPE and compatible PE films. Film thickness, additives, surface treatment and storage conditions can affect adhesive contact and should be included in qualification testing.

Technical Specifications

Application Conditions
Refrigerated Packaging
Used for bags sealed before refrigerated storage or cold transport. The temperature of the film at the time of application should be included in qualification.
Industrial Bag Closure
Suitable for HDPE bags used for packaged materials, components and industrial products where permanent closure is required during cold handling or storage.
Cold-Chain Handling
Applicable where sealed bags are subsequently exposed to low temperatures. Evaluation should cover both the sealing stage and the expected storage or transport conditions.

Selection Criteria
Film Structure
Confirm the film material, thickness, bag construction and surface condition. Film additives and surface treatment can influence adhesive contact.
Temperature Range
Define the application temperature, minimum film temperature and expected storage or transport temperature. These values determine the appropriate adhesive construction.
Tape Geometry
Tape width, adhesive width and liner extension should correspond with the sealing area, bag opening and application method.
Roll Format
Specify roll length, core size, winding direction and packaging format according to the converting process or manual application method.

Selection Criteria
Film Structure

Temperature Range
Define the application temperature, minimum film temperature and expected storage or transport temperature. These values determine the appropriate adhesive construction.
Tape Geometry
Tape width, adhesive width and liner extension should correspond with the sealing area, bag opening and application method.
Roll Format
Specify roll length, core size, winding direction and packaging format according to the converting process or manual application method.

Qualification & Customization
Film Testing
Samples can be evaluated on the actual HDPE or PE film at the intended application temperature, pressure and dwell time. This establishes practical compatibility before production approval.
Dimensional Matching
Tape width, adhesive width, liner extension, roll length and core size can be adjusted to the bag design and application process.
Sample Reference
An existing tape sample, finished bag or technical drawing can be used to define tape dimensions, adhesive position and roll requirements before production.

Procurement Information
For specification review, provide the film material, film thickness, application temperature, minimum exposure temperature, tape width, adhesive width, liner extension, roll length, core size, application method and estimated quantity. A finished bag or existing tape sample can be included when the closure construction needs to be matched.

Frequently Asked Questions
Can this tape be applied to cold HDPE film?
Yes. The tape can be evaluated for application to cold HDPE film. The actual film temperature during sealing should be included in the qualification conditions.
What determines the suitable temperature specification?
Application temperature, film temperature, HDPE surface condition, adhesive area and subsequent storage or transport temperature are the main selection factors.
Is the tape intended for permanent sealing?
Yes. The adhesive construction is intended for permanent closure of compatible HDPE and PE bags after application.
Can the tape dimensions be customized?
Yes. Tape width, adhesive width, liner extension, roll length and core size can be specified according to the bag construction and application process.
Can samples be tested on an existing bag?
Yes. Testing on the actual bag film can be used to evaluate adhesion, liner removal, sealing geometry and temperature performance before production approval.
What information is required for product selection?
The main information includes film material, film thickness, application temperature, minimum exposure temperature, tape dimensions, roll requirements, application method and estimated quantity.
