Multilayer film technology offers scope for incorporation of different type of functional additives for different layers. Thus films can be tailor made to meet all the inside as well as outside performance requirements as explained earlier.
The different types of performance enhancing additives being used selectively for respective layers are as follows:
Anti Static Agent:
Anti Dust+ Uv Stabilizers & Nickel-Quencher
Light Diffusing Additives:
Diffused+Uv Stabilizers & Nickel-Quencher
Anti Fogging Additives:
Anti Drip+ Uv Stabilizers & Nickel-Quencher
The dosage levels of additives can be optimized according to each layer thus resulting into significant cost savings.
Any undesirable defects in one of the layers of film resulting due to any impurity in polymer/additive master batch can be masked with the remaining two layers.
Significant improvements in mechanical properties can be achieved with addition of minor component of high performance polymers in individual layers.
Multilayer films are found to demonstrate superior moisture barrier properties. Co-extrusion technology for the multilayer films has the best scope for lading the film with these requisite properties. As a product of latest technology & inculcation of various specialized functions like uv, ir / thermal stability, diffusion, anti-fog, anti-sulphur, anti-dust, etc.
