Introduction
In the pet food industry, packaging plays a strategic role in protecting products and enhancing brand value. PET packaging is widely used for flexible pouches, trays and jars for wet and dry food, snacks and supplements, thanks to its transparency and resistance. Aluminum packaging, in formats such as trays, lids and sachets, is appreciated for its excellent barrier properties and shelf-life protection. Metallized packaging, typically based on plastic films with a thin metallic layer, combines lightness with enhanced protection and striking visual effects.
When these solutions are Made in Italy, they gain added value in terms of certified quality, traceable supply chains and refined design, increasingly requested by pet brands seeking distinctive, reliable packs. Market demand is moving toward high-performance, sustainable and visually appealing packaging, capable of conveying care for animals and the environment.
Steba positions itself as a specialized Italian partner able to supply PET, aluminum and metallized packaging for pet products. The following sections will explore materials and structures, performance and safety, design and branding opportunities, sustainability and regulatory aspects, and Steba’s integrated services for supporting pet brands from concept to industrialization.
1. Materials and Structures: PET, Aluminum and Metallized Films for Pet Packaging
1. 1 PET Packaging for Pet Food: Properties and Uses
PET (polyethylene terephthalate) is a strong, transparent and lightweight polymer widely used in pet packaging. It is ideal for thermoformed trays, rigid containers, lidding films and stand‑up pouches where PET acts as the printable outer layer. Key advantages include high mechanical resistance against puncture from kibble or bones, excellent printability for branding, and dimensional stability during high‑speed filling and heat sealing. Steba selects specific PET film grades for wet food, dry food and pet care accessories, converting them with controlled thickness and surface treatments to ensure adhesion of inks, coatings and laminating adhesives.
1. 2 Aluminum-Based Packaging: Maximum Barrier and Shelf Life
Aluminum provides an almost total barrier to light, oxygen and water vapor, essential for protecting fats, sauces and aromas in wet pet food. Typical applications are single‑serve trays, peelable foil lids and multilayer flowpacks containing pâtés or gravies. The aluminum layer prevents oxidation and rancidity, stabilizing nutritional values and organoleptic qualities over long shelf life. Steba supplies aluminum trays, die‑cut lids and laminated foils produced in Italy, with tight control of alloy, temper and coating to guarantee consistent forming behavior and sealing windows on industrial lines.
1. 3 Metallized Films: Lightweight Barrier Alternatives
Metallized films, such as vacuum‑metallized PET or BOPP, deposit a thin aluminum layer onto plastic, offering a lighter alternative to full foil. Their oxygen and moisture barrier is lower than solid aluminum but sufficient for many snacks, treats and dry food pouches requiring medium‑high protection. These films also support glossy, metallic aesthetics. Steba develops metallized laminates that fine‑tune barrier level, stiffness and tear properties while considering cost and recyclability targets, for example PET/met‑PET/PE structures for zip‑pouches.
1. 4 Multilayer Laminates and Advanced Constructions
Modern pet packaging often relies on multilayer laminates combining PET, aluminum and metallized films with sealable inner layers like PE or PP. Polyurethane or solvent‑free adhesives and dedicated tie layers bond these materials, influencing stiffness, curl and aroma retention. The choice of inner sealant governs hot‑tack strength, sealing temperature range and compatibility with retort or pasteurization. Laminate architecture directly affects machinability: coefficient of friction, web flatness and slip must suit vertical or horizontal form‑fill‑seal equipment. Steba provides engineering support to design, prototype and test bespoke structures—such as PET/Alu/PP for retortable trays or PET/met‑PET/PE for snacks—optimizing performance on specific pet packaging lines.
2. Performance, Safety and Functional Features of Pet Packaging
2. 1 Barrier Properties and Shelf Life Optimization
PET, aluminum and metallized films offer graduated barriers to oxygen, moisture and light. Aluminum delivers almost total barrier, ideal for pâtés and gravy-rich wet food. Metallized films balance barrier and flexibility, suiting semi-moist snacks, while PET structures with tailored coatings protect dry kibble and supplements. Correct barrier levels help stabilize aromas and limit fat oxidation, preventing rancidity and off-odors throughout the declared shelf life. Steba engineers multilayer laminates that match each recipe’s sensitivity, from oxygen-critical omega-rich formulations to moisture-sensitive freeze-dried treats.
2. 2 Mechanical Strength, Sealing and Processability
High puncture resistance, tear strength and dimensional stability are essential to avoid leaks during palletization and e‑commerce shipping. Steba specifies films and foils that maintain shape in retort, pasteurization or nitrogen-flushing. Sealing performance is tuned for hot sealing, peelable lids and contamination resistance where fats or gravies may enter the seal area. All materials are validated on high-speed filling and sealing lines, using line trials to minimize jams, mis‑seals and waste while keeping forming, cutting and coding operations stable.
2. 3 Food-Contact Safety and Regulatory Compliance
Pet food packaging must comply with the same food-contact frameworks applied to human food, including EU Regulation 1935/2004, EU 10/2011 for plastics and relevant FDA requirements. Steba conducts overall and specific migration tests on PET, aluminum and metallized laminates, supported by full raw-material traceability and GMP-certified production. Inks, adhesives and coatings are strictly selected for low migration, non-intentional substance control and thermal stability during retort. Batch documentation and periodic audits ensure continuous conformity to Made in Italy quality protocols and international standards.
2. 4 Convenience Features: Easy-Open, Resealability and Portioning
Easy-open lids, laser-scored tear notches and clean-peel foils simplify daily feeding routines, especially for small cans and trays. For dry food and treats, Steba incorporates press-to-close zippers or slider systems that preserve crunchiness after first opening. Portion-controlled aluminum trays and single-serve metallized pouches help owners manage dosage, reducing product waste and overfeeding. Steba’s design teams integrate these convenience options while maintaining required barrier levels and seal integrity, ensuring no compromise on safety or product stability.
3. Design, Branding and Customization of Made in Italy Pet Packaging

4. Sustainability and Regulatory Trends in PET, Aluminum and Metallized Pet Packaging
4. 1 Recyclability of PET, Aluminum and Metallized Structures
Mono-material PET trays and pouches are increasingly favored because they fit established mechanical recycling streams and support circular economy targets. Aluminum, with recycling rates above 70% in Europe, performs excellently in closed-loop systems where recovered metal is re‑used for new packaging. Complex multilayer and metallized laminates remain challenging, as incompatible polymers and thick foil layers hinder separation. Design-for-recycling strategies include switching to single-family polymers, downgauging foil, and using ultra-thin metallization compatible with PET recycling guidelines. Steba supports customers in selecting structures that maintain oxygen, light and aroma barriers while remaining acceptable for recognized recyclability protocols.
4. 2 Lightweighting and Resource Optimization
Lightweighting reduces thickness of PET films, aluminum layers and sealants without sacrificing puncture resistance or seal integrity. In many pet food formats, high-barrier metallized PET can replace full aluminum foil, cutting metal usage while preserving shelf life. Lower pack weight directly reduces transport emissions per ton of product and decreases material consumption per unit sold. Steba’s R& D team fine-tunes gauges, coatings and layer ratios to deliver lighter laminates tailored to specific fill weights and processes, helping brands reach CO₂-reduction targets and optimize palletization without compromising safety or machinability.
4. 3 Compliance with Environmental Regulations and Market Standards
European rules such as the Packaging and Packaging Waste Regulation (PPWR), the Single-Use Plastics Directive and national EPR schemes drive recyclability, recycled content and eco-modulation fees. Internationally, ISO standards and local producer-responsibility laws reinforce these trends. Retailers increasingly demand recyclability certifications, plastic reduction roadmaps and alignment with eco-label criteria. Documentation on material composition, migration compliance, carbon footprint and recyclability assessments is now essential. Steba maintains full traceability across its Made in Italy production, provides technical datasheets and environmental declarations, and adapts PET, aluminum and metallized structures to meet retailer scorecards and brand sustainability charters.
4. 4 Eco-Design and Communication of Sustainability to Consumers
Eco-design for pet packaging focuses on reducing unnecessary layers, favoring mono-material PET where feasible, and ensuring clear end-of-life routes. Practical examples include simplifying laminates, choosing easily removable labels, and printing explicit disposal instructions aligned with local collection systems. On-pack icons, standardized recycling logos, concise claims and QR codes linking to detailed information help pet owners understand how to sort pouches, trays and lids. Environmental performance must always be balanced with barrier properties, product safety and convenience.
