How to Choose Tape Liners

Tape liners are removable layers of a tape construction that play an important role of keeping a tape’s adhesive protected and preserved until the time of use. These liners are commonly made of film and paper materials in several varieties in order to accommodate a wide spectrum of industrial needs.


Film liners are made from durable clear films that add tensile strength to a tape suitable for high speed processes like rotary die-cutting.

Clear Polyester (PET)

Polyester liners (PET) are high strength film liners suited for high speed die-cutting and dispensing. (eg. Green Polyester Tape)

Clear High Density Polyethylene (HDPE)

High Density Polyethylene (HDPE) liners have similar strengths to PET liners allowing for high speed processing and dispensing. (eg. 3M 9172MP)


Paper liners come in different varieties of Densified Kraft and Polycoated Kraft. Densified Kraft liners are made to withstand rotary processing while Polycoated Kraft liners are manufactured to resist moisture and humidity.

Densified Kraft (DK)

Densified Kraft Liners are silicone treated on the adhesive side to cover the tape while die-cutting and are printable on the exposed side. (eg. 3M 927)

Extended Densified Kraft (XL)

Extended Densified Kraft Liners are similar to DK liners but the liner extends beyond the adhesive for easier handling and removal. (eg. 3M 465XL)

Polycoated Kraft (PCK)

Polycoated Kraft Liners are notable for moisture, wrinkling and curling resistance. (eg. 3M 467MP)

Extensible Polycoated Kraft (EK)

Extensible Polycoated Kraft liners build upon the characteristics of the Polycoated Kraft with improved tensile strength to resist tearing. (eg. 3M 950EK)


Adhesive Transfer Tapes in Depth: 468 MP


3M 468 MP is an adhesive transfer tape ideal for bonding metal or plastics with high surface energy. This product is an industry standard and is widely used in the Aerospace, Appliance, Automotive,Electronics, Graphic Attachment and Transportation industries.


3M 468 MP is constructed with 58# Polycoated Kraft, a paper liner that is coated for enhanced resilience to moisture, wrinkling and curling. This liner allows 3M 486 MP the ability for die cutting and high speed processing.


3M 468 MP is constructed with 3M 200MP Acrylic Adhesive. This product requires a dwell time to achieve its maximum bond strength. The product will be initially repositionable immediately after application, but it will achieve a strong bond within minutes of the application and reach its maximum bond over several hours. The cleanliness and temperature of the application surface affect the quality of the bond that this product achieves.


Due to 3M 468MP utilizing an acrylic adhesive care must be taken into the application of the adhesive for an effective bond. The surface should be clean and clear of impurities; prepare application surfaces with the purest possible solvents like 99% ethanol. Maintain atmospheric and surface temperatures at a range between 60°F and 100°F in order to ensure an optimal bond formation.
