Designed for brand owners, product designers, and sourcing leads: follow the playbook, consult the quick-checks, and use the examples to build packaging that looks premium while being production-ready.
Why custom print is a product’s first salesperson
Great printing does more than reproduce a logo. It creates hierarchy, communicates value, and reduces last-second hesitation at point-of-sale or checkout. Print choices — from tactile soft-touch varnish to high-contrast metallic foils — change perceived price position and brand memorability.
This framework focuses on the six material families listed above and shows which techniques consistently deliver higher perceived value while maintaining manufacturability and regulatory fit for categories like Personal Care & Toiletries, Cosmetic Packaging, Pharmaceutical & Healthcare Packaging, and Food & Beverage Packaging.
Polyethylene (PE) often powers squeezable tubes, refill pouches, and consumer tubs. Printing on PE demands respect for its low surface energy: untreated PE repels inks and adhesives. To achieve consistent print quality, surface activation (corona or plasma) or primer coatings are typically applied before printing.
Common print and finishing approaches include flexographic printing for high volume runs, thermal transfer labels for smaller batches, silk-screen for spot-colour opacity, and digital print for short runs with variable data. Consider tactile finishes — soft-touch coatings and spot gloss varnish — to increase shelf presence without heavy added cost.
Compatibility note: for food-contact or toiletries, confirm material grade and use filling guidelines and regulatory statements early in the design phase.
PET offers excellent clarity and stiffness, making it ideal for transparent bottles and display-ready containers. High-resolution digital and offset-litho printing on shrink sleeves, pressure-sensitive labels, and direct printing can produce crisp photography and fine typography.
Decoration options that perform well on PET include full-body shrink-sleeves, UV flexo varnish for spot highlights, cold-foil transfer for metallic effects, and in-mold labeling for tamper-resistance with an integrated finish. Because PET is widely recycled, choose water-based inks and labels compatible with PET recycling streams when sustainability matters.
Applications: personal care, beverage (clear PET bottles), and premium cosmetic jars where transparency supports product visibility.
Polypropylene is a workhorse for jars, closures, and rigid containers. PP supports high-speed printing methods like flexo, pad printing (for curved closures), and digital roll-to-roll when using appropriate primers. PP typically needs surface treatment similar to PE to improve ink adhesion.
PP excels when paired with soft-touch finishes, tactile embossing, or multi-layer label systems. It is a cost-effective choice for household products and daily-use containers, and performs well with tamper-evident closures and refill-friendly wide openings.
For travel kits and refillable systems, reference the Easy Refill Wide Opening guidance when designing neck finishes and print placement.
Aluminum offers a premium tactile and visual canvas: anodised finishes, brushed textures, and cold-forming add perceived value. Printing on aluminum is typically done via lithography, UV flexo on coated sheets, or anodised direct printing. For cylindrical aluminum tubes, lithographic or digital processes are common.
Foil stamping and hot-stamping pair exceptionally with aluminum for durable metallic effects. Embossing or debossing can be combined with lacquer or protective varnishes to protect high-wear areas and create a memorable hand-feel for premium cosmetics and specialty food tins.
Aluminum’s recyclability is strong; specify inks and coatings that do not compromise the metal’s recycling stream when sustainability is a priority.
Tinplate printing (canning, biscuit tins, collectible packaging) leverages lithographic printing to reproduce photographic-quality artwork across wrap-around surfaces. Tinplate allows special coatings including UV varnish, soft-touch, and protective lacquers, which maintain tin integrity and improve scuff resistance.
Because of its structural strength, tinplate supports decorative embossing and complicated die-cut shapes. Use metallic inks carefully — they interact with tin finishes and require tests to ensure long-term adhesion.
Pull inspiration from heritage packaging to create limited-edition collectibles that add resale and gifting value to a brand offer.
Silicone components (sleeves, lids, seals) require printing or marking processes suited to flexible, heat-resistant substrates. Pad printing, UV-curable inks formulated for silicone, and laser etching (for certain silicones) provide durable branding that withstands frequent washing and handling.
Design tip: keep high-contrast graphics simple on silicone. Multi-color photos rarely translate well; instead use strong brand marks, simple icons, and micro-text that reads clearly on small surfaces. Silicone is ideal for reusable travel bottles and leak-proof lids—pair with the Leak-Proof Lid Design guidance.
Silicone & BPA-free options are especially relevant for health-sensitive categories — see product specifications for grades and certification notes.
Design & Production Playbook — print-ready steps
A reproducible hand-off reduces iterations and speeds time to market. Use this checklist for every dieline, regardless of material:
- Final artwork at 300 DPI for raster images; vector for logos. Include 2–3 mm bleed outside cut lines.
- Color profiles: supply CMYK for litho/flexo, or Pantone guides for spot matches. Include lab values for metallics where possible.
- Fonts: convert to outlines or embed fonts. Keep type above 6 pt for legibility on small labels.
- Layering: separate varnish/spot-gloss/foil layers as individual files or swatches.
- Material callouts: note substrate, thickness, print-side (inside/outside), and finish. For PE/PP include whether surface treatment applied.
- Filling, closure & logistics notes: include neck finish, filling temperature constraints, TSA-approved bottle size if applicable. Reference TSA-approved bottle size guidance early for travel kits.

Practical checklists & common pitfalls
Quick pre-press checks — perform these before approving artwork for plate-making or digital runs:
- Confirm substrate and finish, and test adhesion on a production-grade coupon.
- Check critical copy & legal copy against dieline locations (e.g., small print on curved surfaces).
- Proof varnish/foil layers as separations — these are frequently missed and create registration errors.
- Plan for the worst lighting: how does color look under store fluorescents and sunlight?
- For refillable systems, make sure print location avoids high-wear contact points (necks, threads).
Case story — PET label refresh that doubled shelf conversion
A mid-sized personal-care brand replaced low-contrast shrink sleeves with a hybrid PET clear body + cold-foil label. The label used selective matte varnish, a single cross-grain emboss on the logotype, and a shallow deboss on the cap. The results: stronger shelf read at 3 meters, a perceived premium uplift, and a 42% increase in conversion from display tests in targeted retailers.
Key to success: early mock-ups, labelling tests for cold-foil adhesion, and aligning art direction to bottle transparency so the product color became part of the visual composition.
FAQ — quick answers to common print questions
➡️Which printing method is best for short runs and variable data?
Digital printing is the most flexible option for short runs and for variable elements like serial numbers or limited editions. For flexible films (PE/PP), digital labels or thermal transfer on pre-treated films usually perform best.
➡️How to match a brand metallic color on PET or aluminum?
Use cold-foil transfer or Pantone metallic guides. For precision, provide a physical swatch and request a press proof. Metallic ink formulas differ by process, so expect small tolerances and confirm on coupon tests.
➡️Can silicone be printed in full color?
Silicone is best with high-contrast single or two-color prints. Multi-color photographic print rarely holds up; use pad printing with specially-formulated inks and test for washing resistance.
➡️What about recyclability and coatings?
Choose inks and coatings that can be separated or are compatible with the recycling stream. For PET bottles, use mono-material labels or wash-off adhesives where possible. For aluminum and tinplate, avoid polymer coatings that complicate recycling.
➡️How to ensure leak-proof performance for refillable bottles?
Design for the correct neck finish, gasket material, and closure torque. Follow filling guidance early to ensure print placement does not interfere with sealing surfaces. See Filling Guideline for recommended tolerances.
➡️Which certifications or food-contact statements are needed?
Material grade and intended use (food, cosmetics, pharmaceuticals) determine compliance requirements. Request material statements and certificates of compliance for food-contact where applicable. Ask suppliers for migration test data for inks and coatings.
