Heat-shrink plastic film in Milan
product protection, compactness and enhanced presentation
Heat-shrink plastic film processing is an effective solution for protecting, grouping and presenting products in an orderly and secure manner. In Milan, Bio Logistica provides contract shrink-wrapping services integrated into its packaging operations, using suitable polymers and controlled thermal profiles to ensure dimensional stability, uniform adhesion and an appearance consistent with technical specifications. Applications include single-product packaging and multipacks for cosmetics, nutraceuticals and food supplements, with printing, labeling and traceability options linked to the production batch.
When to choose shrink-wrapping
advantages
The use of shrink plastic film is ideal when you need to combine mechanical protection, pack consolidation and visibility of the contents. Heated in a tunnel or hood, the film shrinks significantly, adhering to the product or group of products; once cooled, it retains its new shape, creating a stable, transparent and abrasion-resistant wrap.
The main benefits include: reduced secondary packaging components, greater integrity during transport, neat shelf presentation, the option of promotional bundles and efficient management of mixed batches with minimal graphic variations. This approach is particularly suited to large-scale retail, where promotional frequency and fast setup require adaptable processes.
For shrink-wrapping, we use polyethylene (PE) and polypropylene (PP) films, selected according to transparency, thickness, softening point and barrier performance. Monomaterial solutions designed for easier recycling are available, as are films with additives to improve tear resistance or provide anti-fog properties, useful where appearance must remain consistent in changing environments.
The formats include: individually wrapped packs, multi-pack bundles with or without handles, film-wrapped trays and promotional kits. On request, we can add pre-cut easy-opening features and windows to improve product visibility without compromising mechanical strength.
process and control parameters
The quality of the result depends on the thermal profile and the distribution of tension across the film. Our lines regulate temperature, conveyor speed and dwell times to prevent wrinkles, collapse or excessive tension at the edges.
Checks include:
- verification of shrinkage in all three directions to ensure uniform adhesion;
- monitoring of the actual temperature in tunnels and contact pressure;
- visual inspections and machine vision systems to detect wrinkles, micro-holes or centering defects.
All parameters are recorded to ensure end-to-end traceability and rapid audits. Integration with batch-printing and labeling stations synchronizes data and codes with the packaging cycle.
integration with packaging and logistics
Shrink-wrapping fits into an operational flow that includes receipt, incoming checks, cartoning, flow packing, labelling and batch-sticker application, palletising and, if required, storage.
Planning includes extended windows to absorb peaks and urgent orders, with scheduled format changes and parametric recipes to reduce set-up times. This makes it possible to maintain predictable lead times and consistent quality even for short runs or variable assortments.
fields of use and application scenarios
Common applications include double or triple packs for cosmetic lines, promotional supplement packs with informational gadgets, temporary groupings to optimize internal handling or for setting up point-of-sale displays.
For multiproduct kits, it is possible to insert separators or inserts to prevent critical contact; after shrinking, the film keeps the components aligned and facilitates loading and unloading operations at distribution centers.
quality, safety and sustainability
Our approach focuses on repeatable quality and waste reduction. Where possible, we use films containing recycled material or monomaterial solutions to simplify recovery processes.
Measuring performance indicators (OEE, reject rate, cycle times) supports continuous improvement and reduces rework and line stoppages. For sensitive products, processes are carried out in controlled environments with preventive maintenance procedures and periodic qualification of key parameters.

FAQs
Quali materiali utilizzate per le termoretrazioni?
Principalmente PE e PP, selezionati in base a trasparenza, spessore e requisiti di resistenza; sono disponibili opzioni monomateriale e con additivi dedicati.
I film in plastica con termoretrazioni sono adatti a multipack promozionali?
Sì. La retrazione garantisce compattazione, protezione e visibilità del bundle, con possibilità di apertura facilitata e bollinature informative.
Come garantite la qualità del confezionamento?
Controlliamo profili termici, tempi di permanenza e tensione del film; sistemi di visione verificano difetti e leggibilità dei codici, con tracciabilità completa.
Potete integrare stampa del lotto ed etichette?
Certamente. La stampa on-line e le stazioni di etichettatura sono sincronizzate con la fase di termoretrazione per evitare incongruenze documentali.
È possibile lavorare piccoli lotti o assortimenti variabili?
Sì. Programmiamo cambi formato rapidi e slot dedicati per lanci pilota o campagne stagionali, mantenendo tempi ciclo stabili e qualità costante.
