HSL-1150P Heat Seal Lacquer
TECHNICAL DATA SHEET
A solvent-based, flexible, universal heat seal lacquer developed for liquid and dry food packaging – HSL 1150-P can be applied directly to aluminum, PET, and paper films in a one-step process using rotogravure or roller coating. It ensures tight seals on aluminum, PET, and PS cups used for water, soft drinks, and dairy products. It is also suitable for packaging dry food products such as chocolate, cakes, and cookies.
PRODUCT DESCRIPTION
Stellar HSL-1150-P is a solvent-based heat seal lacquer specially formulated from a combination of polymers and additives. The product can be applied directly in a one-step coating process onto ALU, PET, and paper films. It ensures reliable sealing for APET and PS cups and is therefore versatile for liquid and dry food packaging.

INSTRUCTIONS FOR USE
Suitable Materials ALU, PET, PS, PLA
Application Methods Rotogravure, Roller Application, Semiflexo
Application Rate 3–7 g/m² (dry content)
Viscosity 15–25 s (DIN 53211, 4 mm)
Thinner Ethyl acetate, MEK
Drying 130–160 °C for 5–10 seconds
Optimal drying depends on factors such as machine speed, lacquer application, temperature profile, evaporation, airflow, and humidity. The residual solvent content should be measured and checked regularly.
Sealing values N/15mm
AL / APET → N/15 mm: 9 (Brugger-HSG C 200°C, 1 s, 460 N, tolerance ±2)
AL / PS → N/15 mm: 11 (Brugger-HSG C 200°C, 1 s, 460 N, tolerance ±2)
AL / AL → N/15 mm: 15 (Brugger-HSG C 200°C, 1 s, 460 N, tolerance ±2)
PET / PS → N/15 mm: 10 (Brugger-HSG C 200°C, 1 s, 460 N, tolerance ±2)
The values above depend on the sealing temperature, and adhesion decreases at lower temperatures.
*Recommended for NC-coated paper surfaces.
