Pharmaceutical Package Adhesive for Lamination JY5175/GY5175

Solvent-based two-component polyurethane adhesives tailored for pharmaceutical packaging offer exceptional versatility and performance. They are designed for laminating a wide range of materials crucial in pharmaceutical applications, including PET, BOPP, CPP, PE, AL, NY, VMCPP, VMPET, and more. These liquid polyurethane adhesive are compatible with dry laminating machines operating at various speeds, ensuring flexibility and efficiency in production.

They are specifically formulated to withstand rigorous conditions such as 100℃/30min plastic boiling sterilization, meeting stringent pharmaceutical packaging requirements. With low solvent residue and excellent anti-attenuation properties, these adhesives maintain the integrity and safety of packaged pharmaceutical products. They also demonstrate superior performance in compounding PE structures, enhancing barrier properties and durability for pharmaceutical packaging that demands reliability and quality assurance.

For flexible packaging applications, adhesives need to meet several criteria:

Regulatory Compliance: Adhesives used in food packaging must comply with relevant regulations regarding food contact materials to ensure safety.

Compatibility: They should be compatible with the materials used in flexible packaging, such as various films, foils, and laminates.

Barrier Properties: Adhesives should contribute to maintaining the barrier properties of the packaging to protect the contents from moisture, oxygen, and other contaminants.

Application Method: Depending on the production process, adhesives may need to be applied via techniques like extrusion coating, lamination, or as a cold seal.

1.Physical Datas:

2.Applicable model:

Two-component solvent-based polyurethane adhesive for pharmaceutical packaging.

3.Recommended ratio:

20:4. Actual ambient humidty and printing ink have an obvious influence on the qualities of lamination. It is necessary to adjust the application amount of curing agent or hardener properly according to the actual conditions.

4.Operating conditions:

(1) When diluting, add the solvent to the main agent according to the required solid content, stir it thoroughly,

(2)Then add the curing agent, and stir it evenly before use.

(3) The water content of the solvent ethyl acetate shall not exceed 0.03%, and the alcohol content shall not exceed 0.02%

(4) Working concentration 25%~35%

5.Drying:

The drying device should have sufficient air volume, wind speed and temperature. When the drying system is divided into three sections, the temperature from the membrane inlet to the outlet is controlled between 50~60℃, 60~70℃, and 70~80℃.
