Secondary Packaging of Biscuits: Importance, Types & Benefits

Secondary Packaging of Biscuits: In today’s fast-paced consumer goods industry, the importance of packaging cannot be overstated. While most discussions around packaging tend to revolve around aesthetics or primary packaging—such as the foil wrappers or plastic trays that directly encase biscuits—secondary packaging plays an equally critical role in the product’s journey from factory to shelf to consumer. In this blog post, we will delve deeply into the secondary packaging of biscuits, exploring its functions, types, materials, technologies, industry trends, and its role in supply chain efficiency and sustainability.

What is Secondary Packaging?

Secondary packaging refers to the outer layer of packaging that groups multiple units of a product together. In the context of biscuits, this means the carton boxes, shrink-wrapped trays, or display-ready containers that hold several individual biscuit packs. Unlike primary packaging, which is in direct contact with the product, secondary packaging is not typically seen by the end consumer unless it doubles as retail-ready packaging.

The Role of Secondary Packaging in Biscuit Production

The secondary packaging of biscuits serves multiple strategic purposes beyond mere containment. These include:

1. Protection During Transport

Biscuit packs are relatively fragile and prone to breakage. Secondary packaging provides structural integrity during transit, reducing the likelihood of damage from compression, vibration, or impact.

2. Ease of Handling

Secondary packaging simplifies the handling and movement of goods. A retailer can quickly move a tray or carton instead of dealing with individual packets.

3. Storage Efficiency

Secondary packaging helps maximize space in storage and transport. Standardized carton sizes allow for efficient palletization and stacking.

4. Retail Display & Shelf Management

In some cases, secondary packaging is designed to be shelf-ready or display-ready. These packages can go directly onto store shelves without requiring unpacking, thus saving time and labor at the retail level.

5. Branding and Marketing

Even though secondary packaging is often not directly visible to consumers, in modern retail settings (especially in supermarkets), the carton or display case is sometimes visible. This presents an additional branding opportunity.

Common Types of Secondary Packaging for Biscuits

There are several types of secondary packaging solutions that are widely used in the biscuit industry:

1. Corrugated Cardboard Boxes

These are the most common form of secondary packaging. They are durable, recyclable, and available in various grades. Biscuit packs are usually arranged in a specific pattern inside these boxes to minimize movement and maximize space usage.

2. Shrink-Wrapped Trays

Shrink wrapping involves placing biscuit packs on a cardboard tray and covering them with shrink film. After heating, the film tightens around the packs, creating a compact bundle. This method is lightweight and reduces packaging waste.

3. Display-Ready Cartons

These are designed with perforations or tear-away sections so they can be placed directly onto store shelves. They combine the benefits of transport efficiency with in-store convenience and visibility.

4. Plastic Crates or Bins

Used mainly for reusable supply chain systems, especially in institutional sales, plastic bins are more durable and can be returned and reused multiple times.

Materials Used in Secondary Packaging of Biscuits

1. Corrugated Fiberboard

This material is cost-effective, strong, and widely recyclable. It offers a good balance between protection and environmental responsibility.

2. Low-Density Polyethylene (LDPE) Shrink Film

Used in shrink wrapping, LDPE film is flexible and provides excellent containment. It can be printed for branding purposes as well.

3. High-Density Polyethylene (HDPE) for Crates

HDPE is used for manufacturing durable plastic crates, which can be washed and reused, offering a sustainable alternative in closed-loop logistics systems.

4. Biodegradable Alternatives

With growing environmental concerns, some companies are exploring biodegradable films and corrugated solutions made from recycled materials.

Design Considerations in Biscuit Secondary Packaging

When designing secondary packaging for biscuits, manufacturers must balance various factors:

1. Product Dimensions and Orientation

The dimensions of the primary biscuit packs influence how they are arranged in secondary packaging. Optimal orientation minimizes wasted space.

2. Weight Distribution

Uniform weight distribution helps in stable stacking and reduces the chances of toppling during transport.

3. Ease of Opening

Retailers prefer packaging that is easy to open and set up for display. Perforated edges or tear strips enhance usability.

4. Stackability and Palletization

Secondary packaging should be optimized for stacking on pallets—both in terms of strength and footprint—so as to maximize transport efficiency.

Automation in Biscuit Secondary Packaging

Modern biscuit production facilities often use automated packaging lines. These may include:

Cartoning Machines: Automatically assemble and fill cartons with biscuit packs.
Shrink-Wrapping Machines: Apply shrink film and pass the bundles through heat tunnels.
Robotic Pick-and-Place Arms: Used for high-speed packing with precision.
Vision Systems: Ensure quality control by checking the correct orientation, quantity, and condition of biscuit packs.

Automation helps reduce labor costs, increase throughput, and maintain consistent quality.

Sustainability in Secondary Packaging of Biscuits

Sustainability is a growing concern in the food packaging sector, and biscuit manufacturers are no exception. Here’s how the industry is responding:

1. Material Reduction

By optimizing the design, many brands are reducing the amount of material used without compromising protection.

2. Use of Recycled Content

Corrugated boxes with a high percentage of post-consumer recycled fiber are increasingly common.

3. Reusability and Closed-Loop Systems

In B2B supply chains, reusable plastic crates help reduce waste and cost in the long term.

4. Biodegradable and Compostable Films

Research is underway to replace petroleum-based shrink films with compostable alternatives derived from starch, PLA, or cellulose.

Cost Factors and Economic Impact

While the primary cost drivers in biscuit packaging are raw material prices and labor, secondary packaging can represent a significant chunk of the total packaging budget. Cost components include:

Material Costs: Cardboard, film, adhesives.
Machine Costs: Automation setup and maintenance.
Labor: For manual packing or oversight of automated lines.
Logistics: Efficient secondary packaging can reduce transport costs significantly.

A well-optimized secondary packaging system can actually contribute to cost savings across the supply chain.

Industry Trends and Innovations

1. Shelf-Ready Packaging (SRP)

Retailers like Walmart and Tesco increasingly demand SRP to reduce in-store labor and speed up shelf restocking.

2. Smart Packaging

Some manufacturers are exploring the use of QR codes and RFID tags on secondary packaging for better inventory tracking.

3. Modular Packaging Designs

These are flexible formats that can be used across multiple SKUs, helping reduce tooling and setup costs.

4. Lightweighting Initiatives

Technology-driven design improvements have made it possible to use lighter materials without compromising durability.

Challenges in Secondary Packaging of Biscuits

Despite the many benefits, manufacturers face several challenges:

Fragility of Product: Biscuits are brittle and require careful handling to prevent breakage.
Environmental Regulations: Increasing regulations on plastic and waste are forcing manufacturers to rethink material choices.
Cost Pressures: Rising material costs require innovative cost-saving strategies.
Changing Retail Formats: E-commerce, bulk sales, and modern retail each demand different packaging solutions.

Best Practices for Effective Secondary Packaging

To make the most out of the secondary packaging of biscuits, manufacturers should:

Conduct Packaging Audits regularly to identify inefficiencies.
