Sleeves - Precise and secure packaging for a strong brand image
From the flexible sleeve to the sales-promoting security element: Sleeves revolutionize product presentation and give you a decisive competitive advantage.
Imagine an ordinary spice shaker from the kitchen cupboard. A thin sleeve surrounding the can signals that the product is originally sealed. It carries nutritional information and brand information and can be printed all around with an eye-catching design. Sleeves of this kind combine three functions in one: product protection, tamper evidence and full surface impact for marketing messages. This is precisely why they are widely used in many industries.
Why sleeves are indispensable for modern product packaging
Sleeves have established themselves as a versatile and efficient solution in the modern packaging industry. They offer numerous application possibilities – from complete product wrapping to tamper-evident closure. Sleeves adapt to almost any product shape, enable 360-degree presentation and combine security with aesthetics.
This technology proves particularly valuable for complex container shapes where conventional labels reach their limits. While classic labeling processes can often only use limited areas, sleeving enables complete wrapping with maximum design freedom. This makes sleeves an indispensable element in the marketing mix of modern packaging strategies.
Tamper-evident sleeves are specially developed safety elements that adhere firmly to the product when exposed to heat. Any manipulation immediately leads to visible damage or breakage of the sleeve – a decisive advantage, especially in the food and pharmaceutical industries [1]. The technology is widely used: the spectrum of this security solution ranges from bottle neck seals to complete product wrappings.
Modern Tamper-evident Sleeves combine several levels of safety:
- Visible (overt) security features for immediate recognition
- Hidden (covert) elements for authentication
- Irreversible destruction during opening attempts
- Integration of QR codes and serial numbers for seamless tracking
This technology can reduce the theft rate in the retail sector by up to 40% [2].
Sleeve variants: From Partial sleeves to full-body solutions
The versatility of sleeves is demonstrated by their adaptability to different requirements. Depending on the intended use, different variants are available that offer specific advantages. The full-body sleeve defines itself as a particularly comprehensive solution.
It completely envelops the product and adapts to the contour like a second skin. With 360-degree printing, the Sleeves are folded from flat Film / Foils to form a tube and Gluing / Adhesion. This sleeve process is particularly suitable for products with complex shapes or those that require maximum brand presence. Thanks to the complete wrapping, full-body sleeves also offer increased protection against environmental influences and tampering.
Partial sleeves, on the other hand, only cover certain areas of the product. They are often used when specific zones need to be highlighted or a complete wrap is not practical for technical or aesthetic reasons. Typical areas of application are bottle necks or closures, where they can also serve as protection against tampering.
The decision between a Partial sleeve and a Fullbody sleeve depends on various factors:
- Product design and form complexity
- Marketing and branding requirements
- Safety and security aspects
- Budget and production considerations
Both variants offer specific advantages and can represent the optimum solution depending on the requirements profile.
The integration of QR codes and individual security features extends the range of functions of these sleeves. They not only serve as tamper protection, but also enable unique product identification and contribute to the security of the entire supply chain [3].
Machine technology for precise Sleeves
The perfect application of sleeves requires high-precision machine technology. BERNING Maschinenfabrik has established itself as a specialist in this field and offers customized solutions for a wide range of requirements. The sleeve machines from BERNING are characterized by high efficiency and precision. They achieve Cycles / Beats (timing) of up to 550 cycles per minute with a maximum product throughput height of 370 mm.
Modern sleeving lines work according to a sophisticated, highly automated principle. The process begins with the precise feeding of the product to be sleeved. The sleeve material is fed from the roll as a flat folded tube, unfolded, cut and then applied to the product. Depending on the application, heat is then applied to shrink the sleeve so that it fits snugly to the product contour.
BERNING offers various technologies for different requirements:
- Full-body application for complete product wrapping
- Partial sleeve systems for partial applications
- Tamper-evident solutions for tamper-proof closures
- Multiple packaging systems for containers and multipacks
A particular advantage of the BERNING systems is their flexibility: the machines can be equipped with several sleeve heads, which enables chaotic production of different colored products. This offers decisive advantages over conventional systems, especially for frequent product changes or small batches.
Fast design changes enable flexible production processes.
In modern production, flexibility in design changes is becoming increasingly important. BERNING is responding to this trend with sleevings lines that enable quick and uncomplicated design changes. This technology offers decisive advantages over conventional labeling and packaging solutions.
Whereas with classic direct printing processes, every design change involves considerable retooling effort, sleeve systems allow for quick changes by simply replacing the pre-printed sleeves. The machine itself remains unchanged and generally does not need to be set up again. This reduces downtimes and enables economical production of even small series.
The flexibility of sleeve systems is already being used by manufacturers from various industries. For example, for multiple packaging of grinding wheels or batteries. Here, several products can be stacked and then combined with a single sleeve. Pre-printed sleeves make it possible to implement variants and design changes at short notice without the need for costly retooling of the Packaging lines. This allows production processes to be kept stable, downtimes to be reduced and cost-effective small batches to be produced with high repeat accuracy.
The advantages of a quick design change
- Shortening the time-to-market for new products
- Cost-effective production of small batches and special campaigns
- Rapid response to market changes
- Simple realization of product variants
- Seasonal adjustments without great effort
BERNING’s machine technology optimally supports this flexibility with innovative solutions that are specially designed for frequent product changes. The machines with multiple sleeve heads even enable the parallel production of different designs without changeover times.
EU Packaging Regulation: Legal requirements for modern sleeves
The EU packaging regulation (PPWR) places new requirements on packaging solutions that are also relevant for Sleeves applications. Since 2025, new regulations have been in force that particularly affect the reusability and recyclability of Packagings. Reusable packaging, which may also include certain types of sleeves, may not be offered to end consumers on less favorable terms than disposable packaging [5].
A key aspect of the regulation concerns the coverage rate of the sleeves over the main part of the packaging. This has a significant influence on the sorting options in the recycling process. Excessive coverage can make automatic sorting more difficult and thus impair recyclability. The legislation refers to this and requires a recycling-friendly design [4].
For manufacturers and users of sleeve technologies, this means taking the legal framework into account right from the design and mechanical engineering stage. BERNING develops its systems in a future-proof manner and ensures compliance with all relevant regulations.
Sleeves in various industries: Wide range of applications
Sleeve technology has established itself in numerous industries and offers specific advantages in each case. Whether in the beverage industry, pharmaceutical products, cosmetics or electronics – customized sleeve applications can be found everywhere.
Beverage industry
In the beverage industry, sleeves enable bottles and cans to be completely wrapped with high-quality printing. The technology is particularly suitable for complex bottle shapes and offers maximum design space for marketing and product information.
Pharmaceutical and medical technology
In the pharmaceutical sector, tamper evidence and product protection are paramount. Tamper-evident sleeves ensure the integrity of the packaging and protect against unauthorized access. The integration of holograms and QR codes creates additional layers of security and enables seamless traceability [5].
Cosmetics and body care products
High-quality presentation plays a key role for cosmetic products. Sleeves with metallic effects, soft-touch surfaces or partial finishes enhance the packaging and help to position the brand in the premium segment.
