Tailored Surface & Additive Treatments

Silpack® "H" Line Available Grades

Manufactured by Supreme with specialized additives to meet the most stringent industrial specifications from electronics cleanrooms to exterior civil engineering.

Corona Treated Grade

Enhanced surface dyne level ensures superior adhesion for industrial labelling, identification stencil prints, and adhesive lamination of protective foams.

Anti-Static (ESD) Grade

Engineered with anti-static agents providing surface resistivity of 109 to 1011 ohms, protecting sensitive electronics, semiconductor trays, and PCB dunnage.

Conductive Grade

Formulated with carbon black additives for conductive shielding (< 105 ohms) to drain electrostatic charges in automated electronics assembly lines.

UV Stabilised Grade

Fortified with hindered amine light stabilizers (HALS) to withstand intense solar radiation, preventing brittleness and color fading during outdoor storage and transport.

Food-Grade Suitable

Made from 100% non-toxic, odorless virgin polymer complying with food contact norms, suitable for fresh fruit separators, food processing plants, and cold chains.

Common Treated Grade

Cost-effective workhorse grade for civil construction floor protection, false ceiling thermal barriers, waterproofing membrane protection, and general packaging.

Versatile Engineering Utility

Silpack® "H" Line Industrial Applications

Trusted by packaging engineers, plant managers, and civil contractors across Gujarat for demanding industrial requirements.

Reusable Transit Packaging

Custom fabricated returnable tote boxes, collapsible transit containers, and divider partitions for automotive components and machinery spares.

Construction Floor Protection

High-impact protective boards laid over marble, granite, wood, and tile flooring during construction, interior fit-outs, and renovations to prevent scratches and chipping.

False Ceilings & Partitions

Waterproof, non-porous false ceiling tiles, cleanroom interior linings, and temporary wall partition panels that resist humidity and washdowns.

Component Separator Plates

Precision cut interlayer tier sheets for stacking glass bottles, aluminum cans, auto parts, and precision machined components on pallets without vibration damage.

Waterproofing Membrane Guard

Tough puncture-resistant protective layer applied over basement waterproofing membranes, bridge decks, and retaining walls prior to soil backfilling.

Cold Storage & Insulation

Dead-air vertical flute chambers act as an effective thermal insulation barrier inside refrigerated transport vans, cold storage rooms, and food processing facilities.
