Echo Simplex Boards are 3-layer PP Honeycomb extruded sheets manufactured using polypropylene in homo polymer, co polymer, and ter polymer formulations. Unlike single-layer PP flute sheets, the unique three-layer honeycomb core structure delivers significantly superior strength, rigidity, and reusable life across industrial applications.
The circular honeycomb core provides equal strength in both machine and transverse directions — making Echo Simplex Boards the ideal replacement for PP corrugated sheets, cardboard, and plywood in packaging, protection, and industrial applications. Available in a wide GSM range from 200 to 3500 GSM, Echo Simplex Boards can be customized for virtually any industrial requirement.
Edge sealing, corner rounding, screen printing, and custom colour options are all available — enabling complete customization for branded and functional applications across industries.

Echo Duplex Boards are advanced 4-layer PP Honeycomb extruded sheets designed for heavy-duty industrial applications, insulation requirements, and weight-reduction solutions. The four-layer construction delivers significantly higher load-bearing strength and rigidity compared to standard 3-layer simplex boards.
With a GSM range of 2000 to 7000 GSM and thickness options from 8mm to 18mm, Echo Duplex Boards are engineered for demanding structural, protective, and insulating applications where standard sheets are insufficient. The double-layer honeycomb core provides enhanced impact resistance, improved thermal insulation properties, and superior dimensional stability.

Echo 5X Boards represent the pinnacle of PP Honeycomb sheet engineering. Mutual Industries Limited is the only Bubble Guard manufacturer in India to produce 5-layer PP Honeycomb sheets — delivering unmatched structural performance for the most demanding industrial applications.
The 5-layer construction creates an extraordinarily rigid, strong, and durable board that is still significantly lighter than wood, MDF, or metal alternatives. This unique combination of high strength and low weight makes Echo 5X Boards the ideal choice for heavy-duty packaging, furniture substrates, automotive applications, and industrial weight-reduction programmes.
With a GSM range of 2000 to 7000 GSM and thickness from 8mm to 18mm, Echo 5X Boards deliver performance that no other Bubble Guard manufacturer in India can match.

Echo ESD Boards are specially engineered PP Honeycomb sheets designed for anti-static and electrostatic discharge (ESD) sensitive applications. Developed to protect electronic components from static damage during packaging, storage, and transit, Echo ESD Boards are available in three variants — Anti-static, Dissipative, and Conductive — covering the full spectrum of ESD protection requirements.
Unlike conventional packaging materials that can generate and accumulate static charge, Echo ESD Boards actively control electrostatic discharge — providing reliable, consistent protection for PCBs, semiconductors, electronic assemblies, and sensitive components.
All three variants are available across the full GSM range and diameter options — enabling complete customization for specific electronic packaging and handling requirements.
