Primary Packaging of Biscuits: Materials, Functions & Innovations

Primary Packaging of Biscuits: Biscuits are one of the most widely consumed snack products globally, enjoyed by people across all age groups. Their crisp texture, sweet or savory flavors, and long shelf life make them an ideal on-the-go treat. However, maintaining the freshness, quality, and safety of biscuits until they reach the consumer requires careful consideration of packaging—especially primary packaging.

In this blog post, we will explore the critical role of primary packaging of biscuits, its material composition, technological innovations, and how industry trends are shaping the future of biscuit packaging.

What is Primary Packaging?

Primary packaging refers to the first layer of packaging that comes in direct contact with the product. For biscuits, this layer plays a vital role in protecting the contents from moisture, oxygen, breakage, and contamination. While secondary and tertiary packaging (such as cartons and shipping boxes) offer logistical and branding support, it is the primary packaging of biscuits that ensures the product remains fresh, safe, and appealing to consumers.

Key Functions of Primary Packaging for Biscuits

The primary packaging of biscuits must fulfill several essential roles:

1. Protection

Biscuits are brittle and sensitive to moisture and oxygen. The packaging must:

Prevent physical damage during transportation.
Protect against moisture to avoid sogginess.
Block oxygen to prevent oxidation and flavor loss.
Keep out contaminants such as dust, insects, or microorganisms.

2. Preservation

Biscuits have relatively low moisture content, but once exposed to humidity or air, they quickly lose crispness. The right packaging maintains their textural integrity, flavor, and shelf life.

3. Convenience

Consumer convenience is another critical factor. The packaging should allow:

Easy opening and resealing.
Portability for on-the-go snacking.
Clear visibility of expiry date and ingredients.

4. Branding and Information

Primary packaging is also a canvas for brand identity. It communicates:

Brand logo and colors.
Nutritional facts.
Allergen information.
Promotional content or QR codes for engagement.

Common Materials Used in the Primary Packaging of Biscuits

The packaging material must combine mechanical strength with barrier properties. The most commonly used materials include:

1. Plastic Films

Polypropylene (PP) and its variants dominate the primary packaging of biscuits due to their versatility and cost-effectiveness.

BOPP (Biaxially Oriented Polypropylene):
- Excellent clarity and gloss.
- Good moisture barrier.
- Widely used in flow-wrap packaging machines.
MET-BOPP (Metallized BOPP):
- Enhanced barrier properties.
- Reflective surface adds premium appearance.
CPP (Cast Polypropylene):
- Offers good seal strength and flexibility.
- Often used as a sealing layer in laminates.

2. Aluminum Foil Laminates

In high-end products or where extended shelf life is critical, aluminum laminates provide exceptional barrier properties against light, oxygen, and moisture.

3. Paper-Based Packaging

Although less common due to poor moisture resistance, paper is often used in combination with plastic or wax coatings. It supports brands looking for eco-friendly or rustic packaging aesthetics.

4. Biodegradable and Compostable Films

With growing environmental concerns, some manufacturers are transitioning to:

PLA (Polylactic Acid)
Cellulose-based films
Starch blends

These offer a lower environmental footprint, although they may compromise slightly on barrier performance and cost.

Types of Primary Packaging Formats for Biscuits

Different packaging styles are used depending on biscuit type, market segment, and consumer expectations.

1. Pillow Packs (Flow Wraps)

The most common form.
Biscuit stacks are horizontally or vertically loaded into a plastic film.
Sealed at both ends and along the back.
Automated and cost-effective.

2. Tray Packs

A plastic or paper tray holding biscuits is sealed with a film or placed inside a cardboard box.
Offers better protection and presentation.
Common in premium biscuits or sandwich creams.

3. Sachet or Pouch Packs

Smaller portions, often used for on-the-go consumption.
Used for mini cookies or biscuit bites.
Single or multi-serving pouches.

4. Canisters and Tins

Used for premium or export-grade biscuits.
Excellent for long shelf life and reusability.
Significantly higher packaging cost.

5. Clamshells and Blister Packs

Rigid plastic containers with individual compartments.
Used for novelty biscuits or gourmet cookies.

Packaging Technologies in Biscuit Manufacturing

To optimize efficiency, many biscuit manufacturers employ automated packaging lines. Key technologies include:

1. Horizontal Form Fill Seal (HFFS) Machines

Used for pillow packs and flow wraps, these machines form the package, fill it with biscuits, and seal it—all in one motion.

2. Vacuum and Modified Atmosphere Packaging (MAP)

Vacuum-sealing reduces oxygen exposure.
MAP replaces oxygen with inert gases like nitrogen to prolong freshness.

3. Cold-Seal Packaging

Heat-sensitive products like chocolate-coated biscuits use cold-seal adhesives instead of heat to avoid melting.

4. Zipper and Resealable Features

Zipper locks or peel-and-seal labels enhance reusability.
These are increasingly common in multi-serve packs.

Sustainability in Primary Packaging of Biscuits

Environmental concerns are driving major changes in packaging design. Brands and consumers alike are demanding eco-friendly packaging without compromising product safety.

1. Reducing Plastic Content

Many brands are switching from multilayer films to mono-material laminates, which are easier to recycle.

2. Recyclable and Compostable Films

PLA, cellulose films, and other biodegradable options are emerging, though they may not match traditional plastic in barrier performance.

3. Paper-Based Alternatives

Coated paper or waxed paper is used in niche, environmentally conscious brands. These formats must still provide adequate moisture barriers.

4. Packaging Optimization

Reducing pack size, switching to lightweight materials, and optimizing pack shapes can lead to lower carbon footprints.

Market Trends Influencing Biscuit Packaging

Several broader market trends are influencing how biscuits are packaged today:

1. Health and Wellness Trends

Consumers increasingly prefer portion-controlled packaging to limit calorie intake. This has led to the rise of:

Snack-size pouches.
100-calorie packs.
Individually wrapped servings.

2. On-the-Go Lifestyles

Portable, resealable, and tamper-evident packaging appeals to busy consumers. Resealable zippers and easy-tear openings are now standard.

3. Premiumization

Luxury and artisanal biscuits come in visually appealing, protective packaging such as embossed tins or laminated boxes with trays.

4. Smart Packaging

QR codes, NFC chips, and AR-based storytelling are being integrated into packaging to boost customer engagement and traceability.

Challenges in Primary Biscuit Packaging

Despite advances, the industry faces several challenges:

Balancing cost and sustainability: Eco-friendly materials are often more expensive.
Regulatory compliance: Materials must meet food safety regulations in every country they are sold in.
Barrier performance vs recyclability: Many high-barrier materials are non-recyclable.
Breakage issues: Lightweight packaging may not offer sufficient protection in transit.

Case Studies: Brands Innovating in Biscuit Packaging

1. Parle-G (India)

India’s most iconic biscuit uses a simple wax-paper laminated plastic pack, focusing on affordability and wide reach. However, Parle has initiated trials with recyclable materials to reduce environmental impact.

2. Oreo (Mondelez)

Oreo’s packaging varies by region—from resealable flow packs to mini bite pouches. In select markets, Mondelez has introduced fully recyclable packaging with bold branding and smart labeling.

3. Walkers Shortbread (UK)

This heritage brand uses foil-lined boxes and tins that reflect a premium, traditional feel. They’ve started transitioning to paper-based wraps to align with sustainability goals.

Conclusion: Primary Packaging of Biscuits

The primary packaging of biscuits plays a vital role in maintaining freshness, protecting against contamination, and delivering brand value. With consumers becoming increasingly aware of both product quality and environmental impact, the demand for innovative, sustainable, and functional packaging is only set to grow.

Whether you’re a manufacturer, brand strategist, or packaging technologist, understanding the nuances of biscuit packaging is crucial for success in today’s competitive FMCG landscape.

As materials and technologies evolve, so too will the ways we package and enjoy biscuits—delivering not only taste and convenience but also environmental responsibility.
