When it comes to safety, Bagla Group is a recognized leader. Innovative manufacturing techniques, strict quality controls and our certified management system set high standards within the packaging industry. Place the durable and reliable sealing of your valuable goods in the hands of a trustful partner!
Technology - State-of-the-art technology, continuous quality controls and highly motivated employees allow us to pioneer the flexible and directive production of self-adhesive tapes. Our production plants from Milan, Italy operate with meticulous accuracy and efficiency. Depending on the product, our coating machines apply exactly 12 - 25 gr/m² of adhesive to up to 18,000 m film reels. These so called "jumbos" are further processed on our fully automated, high-performance slitting and packaging lines in widths of 12 to 300 mm and roll lengths between 50 and 2,000 m.
- High production accuracy.
- Premium self-adhesive tape quality.
- A visionary partnership that invests in technology and training.
- Continuous improvement processes at all production levels.
Permanent quality control means more than just monitoring production. At Bagla Group, we use internationally established test methods to control every step of the process from raw material to finished product. Driven by innovation, special practical trials were developed to enhance both products and processes.
What is essential for an optimal sealing of cardboard carton?
- Adhesion Strength
Peel adhesion has to be evaluated in combination with immediate tack (quick stick) and shear adhesion measured on a carton. High adhesion values on steel do not automatically guarantee a proper closure of the carton, nor do low adhesion values necessarily mean poor tape quality. Optimum seal safety lies in the perfect balance of adhesion, tack and shear strength on a carton.
- Tack (Immediate Adhesion)
Tack refers to the initial adhesion. The tack value is ascertained by the rolling-ball test and cannot be interpreted without reference to adhesion and shear strength. A good rolling-ball tack feature indicates a strong adhesive that covers the cardboard fibres straight after its application. Acrylic self-adhesive tapes, for instance, show good tack results at minimal shear strength values. It is therefore important that tapes with an Acrylic adhesive are applied with maximum pressure. Also, a period of up to 24 hours is necessary to achieve an optimal liaison with the carton surface.
- Shear Strength on Cardboard Surface
An accurate statement regarding the holding power of a self-adhesive tape is only possible when considering adhesion strength, immediate tack and carton quality at the same time.
The surface of a carton should not contain any release agents like silicone or wax and has to be absolutely dry and dust-free. A strong focus is requested on exact carton pressing and folding parameters as well as taping.
- Contact Pressure
Without sufficient pressure, the adhesive cannot bond with the carton surface to secure a reliable carton closure. This is why you often hear packaging tapes being referred to as “Pressure Sensitive Tapes” (PST). Pressure is especially important when applying the tape manually with a dispenser. In the case of machine rolls, packaging machines automatically assure that the correct sealing pressure is applied.
- Application Temperature
Too cold and the adhesive becomes brittle; too warm and it can get greasy. Even if adhesive tapes made from natural rubber perform in extreme temperatures, they have to be processed at room temperature to ensure permanent sealing.
We care about the environment - we care about people. Environment protection and sustainability are deeply rooted in our company's policy. Regular internal and external audits confirm we operate according to governmental regulations and fulfil legal requirements.
What does sustainability mean to Bagla Group?
- Responsible use of natural resources.
