Dairy Packaging: Food-Safe PE Films for Milk, Yoghurt, and Cheese Products
Dairy products—milk, yoghurt, ayran, cheese, butter, cream, and ice cream—are among the most perishable items in the food supply chain. They are highly sensitive to light, oxygen, temperature fluctuations, and microbial contamination, demanding packaging that provides uncompromising protection from processing plant to consumer refrigerator. Dairy packaging in polyethylene film format serves critical functions: forming liquid-tight sachets for milk and ayran, creating protective wraps for cheese blocks, providing shrink bundles for yoghurt multi-packs, and offering lidding films for cup-format dairy products.
Aydoğan Plastik manufactures food-grade PE dairy packaging films and bags that combine strict regulatory compliance with the barrier, seal, and mechanical performance this sensitive product category demands. Our film extrusion lines produce multi-layer films with precisely controlled properties for each dairy application, from ultra-thin sachet films to heavy-gauge cheese vacuum-pack materials.
Applications Across the Dairy Sector
Milk Sachets & Pouches
Sachet milk remains a major packaging format across Turkey, the Middle East, Africa, and South Asia, offering an affordable alternative to rigid carton and bottle formats. Our milk sachet films are produced from food-grade LDPE and LLDPE with excellent seal strength, puncture resistance, and opacity. White-pigmented films block light transmission that degrades milk proteins and vitamins, while the PE structure provides a clean, neutral flavour profile with no migration of packaging components into the product.
Milk sachets are filled on high-speed vertical form-fill-seal (VFFS) machines that demand films with precise thickness tolerances, consistent slip properties, and reliable hot-tack performance. Our films are optimised for the specific machine parameters of leading VFFS equipment brands, minimising downtime and maximising fill accuracy.
Ayran & Fermented Dairy Pouches
Ayran, kefir, and buttermilk pouches present particular sealing challenges due to the product’s acidic pH and tendency to splash during filling. Our wet-seal capable films deliver reliable hermetic closures even when liquid is present on the sealing surfaces, preventing leaks that cause product loss and retail rejection. Film formulations are tested for compatibility with acidic dairy products to ensure no flavour interaction or film degradation occurs during the product’s refrigerated shelf life.
Cheese Packaging
Cheese packaging requirements vary enormously across the category. Fresh cheeses (feta, mozzarella, cottage cheese) need moisture-retaining packaging that prevents drying while maintaining an anaerobic environment. Aged and hard cheeses (cheddar, parmesan, gouda) require oxygen-barrier packaging that prevents surface mould and oxidative flavour changes. Our PE films serve as the sealant and moisture-barrier layer in laminated cheese packaging structures, while vacuum-compatible formulations enable oxygen-exclusion packaging for extended-shelf-life applications.
Shredded and sliced cheese products demand films with controlled anti-fog properties to maintain visual appeal in retail refrigerated displays, alongside anti-block characteristics that prevent cheese slices from bonding together inside the pack.
Yoghurt Multi-Pack Shrink Bundles
Individual yoghurt cups are frequently bundled in multi-packs of 4, 6, or 8 units using PE shrink film. Our shrink-grade dairy films deliver consistent shrink ratios for uniform bundle appearance, with high clarity that allows consumers to read the individual cup labels through the outer wrap. The film must shrink tightly enough to hold the bundle securely during transport without crushing the cups or distorting the labels—a balance our formulations achieve through precisely controlled shrink force and shrink temperature parameters.
Butter & Cream Packaging
Butter wraps and cream container lidding films must resist fat migration—the tendency for dairy fats to penetrate the film structure, causing delamination, print degradation, and barrier failure. Our PE films formulated for butter and cream applications incorporate fat-resistant inner layers that maintain structural integrity even in prolonged contact with high-fat dairy products. For butter blocks, our films provide the dead-fold and conformability needed for neat, professional wrapping on automatic butter-packaging machines.
Technical Specifications
Film Thickness & Material
Dairy packaging films range from 30 to 100 microns. Milk sachets use 40–60 microns, cheese vacuum-pack layers 50–80 microns, yoghurt shrink bundles 30–50 microns, and butter wraps 40–60 microns. Our co-extrusion lines produce multi-layer structures with food-contact-compliant inner layers, mechanical core layers, and print-ready outer layers.
All dairy-contact films are produced from food-grade resins that comply with EU food-contact regulations and relevant international food safety standards. Migration testing certifies that no harmful substances transfer from the packaging to the product. Certificates of compliance are available upon request.
Light Barrier
UV and visible light exposure causes photo-oxidation of dairy fats and destruction of riboflavin and other light-sensitive vitamins. White-pigmented, black, and metallised PE films provide varying degrees of light protection calibrated to each product’s sensitivity. Milk sachets typically use white opaque films that block more than 95 percent of incident light, while cheese and butter applications may use printed opaque structures that combine light barrier with brand communication.
Seal Performance for Liquids
Liquid dairy sachets must withstand hydrostatic pressure from the product, drop impacts during distribution, and squeeze forces during consumer handling—all without leaking. Our seal formulations deliver high seal strength and peel resistance, verified through burst-pressure testing and drop-impact testing in our quality control laboratory. Wet-seal capability ensures reliable closures on high-speed VFFS lines where milk splash is unavoidable.
Printing & Branding
Up to 8-colour flexo printing enables dairy brands to build strong visual identity on packaging. Product imagery, nutritional panels, ingredient lists, best-before date coding areas, and brand graphics are printed with precise registration. Our graphic design team provides digital mockups for pre-production approval. Lamination options protect print quality and enhance shelf presence.
Production Process
Our integrated, ISO-certified facility manages the entire dairy packaging workflow. Film extrusion produces food-grade base films, printed orders proceed to printing, followed by slitting and cutting. Every batch undergoes quality control testing for thickness, seal strength, barrier values, migration compliance, and print accuracy. Finished goods ship from warehousing and shipping. Visit about us or contact us for tailored dairy packaging solutions.
Sustainability
Production waste is recycled through our recycling facility. PCR PE content is available on request for non-food-contact applications. Mono-material PE dairy packaging supports end-of-life recycling within existing PE waste streams. The dairy sector’s shift toward recyclable packaging is accelerating as major retailers introduce mandatory recyclability targets for supplier packaging across all product categories. Aydoğan Plastik supports this transition with mono-PE formulations that deliver the barrier, seal, and food-safety performance dairy products demand while remaining fully compatible with established PE recycling infrastructure.
