The Ultimate Guide to Flexible Packaging: Finishes, Thickness, and Uses
Flexible packaging is a game-changer for many industries, offering durability, versatility, and excellent branding opportunities. Whether you're in the coffee business, fertilizers, or FMCG, choosing the right material and finish can make all the difference. At INKT, we specialize in crafting the perfect flexible packaging solutions to suit your needs. Let’s break down the key considerations.
Different Finishes for Flexible Packaging
Finishing touches are what give packaging its final look and feel. The right finish enhances the product’s visual appeal while providing additional protection. Here are some of the most common finishes:
Matte Finish – Sleek and sophisticated, matte finishes are great for premium brands, offering a smooth, non-glossy look that exudes quality.
Gloss Finish – Eye-catching and vibrant, gloss coatings enhance colours, making your product pop on the shelves.
Soft-Touch Finish – A premium choice, soft-touch laminate adds a velvet-like texture to the packaging, giving a luxurious feel.
Metalized Finish – A high-end look with an added layer of barrier protection, often used in food and beverage packaging.
Spot UV – Perfect for highlighting specific design elements with a glossy, raised effect while keeping the rest of the packaging matte.
Understanding PE Thickness and When to Use Thicker PE
Flexible packaging is commonly made from polyethylene (PE), and its thickness is crucial in determining durability, flexibility, and protective qualities.
Lightweight PE (50-80 microns) – Ideal for small snack packs, single-serve pouches, and sachets where flexibility and cost-efficiency are key.
Medium-Thickness PE (80-150 microns) – A great all-rounder used for food packaging, cosmetic pouches, and larger FMCG products.
Heavy-Duty PE (150-250 microns) – Required for bulkier, heavier items like fertilizers, pet food, and large-volume liquid packaging.
Thicker PE is especially important when extra durability is needed, such as:
Protecting against punctures and tears
Ensuring product freshness for extended periods
Withstanding transportation and handling stresses
Coffee Bags & The One-Way Valve: Why It Matters
Ever wondered why coffee bags have that little valve on the front? That’s a one-way degassing valve, and it plays a crucial role in keeping coffee fresh.
Prevents Bag Expansion – Freshly roasted coffee releases carbon dioxide. Without a valve, this gas would cause the bag to puff up and potentially burst.
Maintains Freshness – The one-way valve lets CO2 escape without letting oxygen in, keeping coffee beans fresher for longer.
Enhances Shelf Life – By reducing oxidation, the valve helps maintain the coffee’s aroma and flavour profile for an extended period.

Digital Printing vs. Gravure Printing: Short Runs vs. Long Runs
Printing method selection is crucial when considering cost, quality, and order size.
Digital Printing – Ideal for short-run jobs and multiple design variations, digital printing offers cost-effective solutions without the need for printing plates. It’s perfect for startups, test runs, or seasonal packaging where flexibility is key.
Gravure Printing – Best suited for high-volume production, gravure printing delivers the highest quality, vibrant colours, and durability. While the initial setup costs are higher due to engraved cylinders, it becomes cost-effective for long print runs.
When choosing between the two, consider:
Short runs (under 10,000 units) – Digital printing is the best choice, offering quick turnarounds and easy customization.
Long runs (50,000+ units) – Gravure printing provides the best return on investment with exceptional colour accuracy and longevity.
Mid-sized runs (10,000-50,000 units) – Depending on budget and quality requirements, either method could be used.
