Packaging manufacturers in India operate under a demanding combination of cost, speed, quality and sustainability requirements. A converter may need to run high-volume production while managing changing substrates, customer specifications, environmental expectations and increasingly complex packaging structures.

These pressures make sustainable chemical solutions more than an environmental discussion. They are becoming part of formulation, procurement and production decisions.

For packaging manufacturers, the question is not simply whether a chemical is described as sustainable. The more useful question is whether a formulation can reduce environmental impact while meeting the technical and commercial requirements of the actual production process.

India’s Packaging Industry Needs Application-Specific Chemistry

Packaging covers a wide range of formats, from paper bags and folding cartons to flexible laminates, labels and specialised industrial packs.

Each format creates different chemical requirements.

A paperboard carton may prioritise water-based inks and adhesives. A multilayer flexible package may require solvent-based lamination chemistry. A premium label may need UV-curable ink or UV coating.

This diversity makes a single sustainability solution unrealistic.

Innokan’s portfolio reflects this application-based approach through water-based, solvent-based and hot melt adhesives, along with water-based, solvent-based and UV-curable inks.

What Makes a Chemical Solution Sustainable?

A sustainable chemical solution can be evaluated through several dimensions:

• VOC emissions
• Energy requirements
• Material efficiency
• Waste generation
• Worker exposure considerations
• Process efficiency
• Durability
• Recyclability compatibility
• Raw material sourcing
• End-of-life considerations

Not every product needs to optimise every factor equally.

For example, a high-performance adhesive may deliver longer service life, while another formulation may reduce solvent use. Both factors can matter depending on the application.

Sustainability therefore requires a broader lifecycle view.

The OECD describes sustainable chemistry in terms of efficient, effective and safer chemical products and processes, alongside resource efficiency and pollution prevention.

VOC Considerations in Packaging Production

VOC management is an important issue for many printing and adhesive processes.

Solvent-based systems use organic solvents that evaporate during drying. They can provide useful properties such as rapid drying and strong adhesion, but require appropriate ventilation and emission-management practices.

Water-based systems use water as the primary carrier and can reduce VOC emissions in suitable applications.

Innokan’s water-based adhesive technology is positioned for applications including folding cartons, labels, bookbinding and selected laminating uses, with low VOC emissions as a key characteristic.

The important word is “suitable.”

Water-based chemistry may require different drying conditions, especially on non-porous substrates. A packaging manufacturer should therefore evaluate the entire process rather than selecting a formulation based on one environmental metric.

Printing Chemistry Has a Direct Production Impact

Ink influences both visual appearance and production performance.

A packaging converter may need:

• Strong substrate adhesion
• Consistent colour
• Fast drying
• Abrasion resistance
• Moisture resistance
• Chemical resistance
• Stable viscosity
• Reliable press performance

Innokan’s portfolio covers three broad ink technologies: water-based, solvent-based and UV-curable inks.

Water-based inks are particularly relevant to paper and cardboard applications. Solvent-based inks can provide rapid drying and adhesion on non-porous materials such as films, foil and metal. UV-curable inks polymerise under UV exposure and can support applications requiring rapid curing and durability.

The correct choice depends on the substrate, press, speed and final application.

Adhesive Selection Is a Packaging Engineering Decision

An adhesive is not simply a bonding material. It becomes part of the packaging structure.

When choosing an adhesive, manufacturers should examine several factors.

Substrate Combination

Film-to-film, film-to-foil, paper-to-board and other structures can behave differently.

Required Bond

Peel strength, cohesion and durability requirements vary by application.

Drying or Curing

The adhesive must develop sufficient bond strength within the available production window.

End-Use Conditions

Temperature, humidity, chemicals and mechanical stress can influence long-term performance.

Sustainability Target

VOC reduction, energy use, waste and end-of-life compatibility may influence the formulation choice.

Innokan’s solvent-based adhesive range, for example, is designed for applications involving plastics, metals and laminates where high bond strength and resistance are required.

Coatings Can Reduce the Need for Additional Materials

Functional coatings can sometimes provide a required surface property without adding a separate structural layer.

Heat seal coatings can provide sealing functionality. UV coatings can add protection and visual enhancement. Release coatings can control how an adhesive-backed material separates from its liner.

Innokan’s coatings portfolio includes these three categories.

The sustainability benefit, however, must be assessed in the context of the complete packaging structure.

A thinner coating may reduce material use, but only if it maintains the required function. A recyclable structure may require specific coating and adhesive chemistry to preserve its intended end-of-life route.

Recyclability Requires System-Level Thinking

Packaging recyclability is not determined by one ingredient alone.

The overall structure can contain several materials and chemical layers. Adhesives, inks and coatings may affect processing, separation or material recovery depending on the packaging design and recycling system.

India’s Central Pollution Control Board recognises different categories of plastic packaging, including rigid, flexible, multilayered and compostable packaging within its plastic-waste management framework.

This reinforces the need for packaging companies to consider structure and end-of-life pathways when evaluating new materials.

Cost Versus Sustainability

Cost remains a major factor for Indian packaging manufacturers.

A chemical solution that increases unit cost may still be commercially attractive if it:

• Reduces waste
• Improves line efficiency
• Lowers energy demand
• Reduces downtime
• Simplifies handling
• Improves product yield
• Reduces rejects

Conversely, a lower-cost material may create hidden costs through slow drying, high waste or additional process requirements.

Total cost of ownership is therefore more useful than purchase price alone.

Supply and Manufacturing Considerations

Indian packaging companies also need reliable supply.

A technically strong formulation has limited value if supply consistency is poor.

Procurement teams should examine:

• Batch consistency
• Technical support
• Lead times
• Application support
• Quality-control practices
• Customisation capabilities
• Documentation
• Scalability

Innokan states that its manufacturing and R&D activities are designed to support industrial chemical applications and quality consistency.

How Indian Packaging Manufacturers Can Start

A practical transition does not require changing every chemical at once.

Start with one application.

Measure the current system for:

• VOC profile
• Waste
• Drying time
• Energy use
• Reject rate
• Adhesion
• Print quality
• Production speed

Then compare an alternative formulation under equivalent conditions.

This creates a measurable basis for decision-making.

Where Innokan Fits

Innokan develops adhesives, inks and coatings for industries including packaging and printing. Its R&D approach focuses on formulation, testing and application-specific development.

For Indian converters and packaging manufacturers, that combination can be relevant when sustainability goals need to be balanced against actual line conditions.

Final Takeaway

India’s packaging industry does not need a single “green” chemical technology.

It needs better chemistry decisions.

Water-based, solvent-based, hot melt and UV technologies can each have legitimate roles depending on substrate, equipment, speed, performance and environmental requirements.

The strongest sustainability strategy is therefore application-specific, data-driven and connected to production realities.
