Choosing the right packaging is a critical decision for protecting the product, transporting it safely and presenting it correctly on the shelf. In flexible and industrial plastic packaging (roll films, doypacks, vacuum pouches, stretch and shrink films, resealable pouches), the right structure is determined by weighing product characteristics, protection needs, logistics, consumer expectations, environmental impact and cost together. The following steps help you choose the most suitable plastic packaging for your product.

1. Assess the Product’s Physical Properties

• Product structure: Whether it is liquid, solid, powder, granule or paste determines the packaging type. Liquids and moist products call for high-seal laminated pouches; powders and granules for films with strong heat-seal performance.
• Weight and volume: Light products may only need thin single-layer PE film, while heavy or sharp-edged products require thicker or multi-layer (laminated) structures and high-strength seals.
• Sensitivity: For products sensitive to impact, moisture or light, multi-layer barrier films or metallized structures provide protection.

2. Define the Protection Requirements

• Barrier need: For products sensitive to oxygen, moisture and light, high-barrier films with EVOH, metallized or aluminium lamination are used.
• Chemical compatibility: The packaging film must not react with the product inside. For food-contact products, suitable food-grade PE/PP and lamination structures should be chosen.
• Moisture and temperature: Moisture-proof coatings, vacuum packaging or heat-resistant (retort) pouches preserve the product’s freshness and integrity.

3. Clarify the Functional Requirements

• Transport and logistics: Stretch film for securing pallets, shrink film for grouped packaging, and durable PE bags for bulk and industrial materials. Stackability and space efficiency matter.
• Shelf life: High-barrier and vacuum structures significantly extend the product’s shelf life.
• Presentation and marketing: Shelf-standing doypacks, window or fully printed pouches make the product stand out. 6-colour flexo and 8-colour rotogravure printing deliver sharp, crisp and vivid graphics.

4. Consider Consumer Expectations

• Ease of use: Ziplock closures, easy-tear notches and resealable doypack structures increase customer satisfaction.
• Aesthetics and brand perception: Matte or gloss lamination, spot varnish and high-resolution printing strengthen the brand’s presence on the shelf.

5. Meet Environmental and Legal Requirements

• Sustainability: Mono-material (mono-PE or mono-PP) recyclable structures and thin-gauge films reduce material use.
• Legal compliance: Especially for food and pharmaceutical products, compliance with food-contact regulations, labelling and relevant national rules is essential.

6. Balance Cost and Efficiency

• Gauge optimisation: Optimising film thickness to the need lowers both material and transport costs; overly thin structures can lead to product loss.
• Production-line compatibility: Roll films suited to automatic form-fill-seal lines increase packaging speed and efficiency.
