The Spark Black Poly coated Kraft Paper you’ve described is tailored to meet the specific packaging needs of the imaging industry, particularly for graphic art consumables coated with light-sensitive chemicals.
Structure
Kraft paper coated with black PE (polyethylene)
Applications
Specifically designed for the packing of graphical art consumables, including:
Offset plates
Offset printing blankets
Letterpress plates
Other digital print media
Features
High Strength Base Kraft
The base kraft used is of high strength, providing a dust and pin-hole-free surface for cleanliness during packing.
Special Polymer Resin
The use of a special polymer resin accommodates more carbon black MBs (Masterbatches), requiring only a thin film to achieve the desired light-screening effect. This polymer also exhibits antistatic properties.
Gas Barrier and Moisture proofness
The coated polymer offers gas barrier properties and moisture proofness, crucial for protecting light-sensitive materials.
Heat Sealability
Plates can be placed on the black poly coated surface and then heat-sealed to form a complete enclosure.
Smooth and Dust-Free Contact Surface
The polymer layer provides a smooth and dust-free contact surface to plates, protecting them from damage during transit.
Higher Physical Strength
The laminate exhibits higher physical strength, including breaking strength, tear strength, and impact puncture strength.
Resistance to Curling
The laminate has resistance to curling, ensuring stability during handling and storage.
Additional Protection for Expensive Plates
For expensive plates, Al foil lamination along with the black polykraft system is used, adding an extra layer of protection.
