Recycling improved

 

Less adhesives

 

  • “As a general principle, as for all non-target materials of a recycling process, the amount of adhesives used in a given paper or paperboard item should be optimised to the minimum amount required to achieve its function.”

Packaging & Packaging Waste Regulation

 

  • By 1 January 2030, the manufacturer or importer shall ensure that the packaging placed on the market is designed so that its weight and volume is reduced to the minimum necessary for ensuring its functionality taking account of the shape and material that the packaging is made of.
    (PPWR, Article 9 (1))

Dot Application

Minimum Sizes

 

  • The recyclability is granted for hotmelt adhesives under following conditions:

    • Softening temperature of the adhesive according to R&B: ≥ 68°C

    • Layer thickness (non-reactive adhesives): ≥ 120 μm

    • Horizontal dimension of the adhesive application (in either direction): ≥ 1.6 mm.

Minimum Size Requirements

 

  • Minimum requirements clearly exceeded

  • Dotsize 4mm

  • Dotsize pressed 6mm

  • Thickness 0,24mm

Plug & Connect

 

No alternative in most cases

 

  • Plug and connect: Often higher substrate consumption, contrary to the aim of minimising packaging.

  • Lack of tamper protection for plug-in connections.

  • Implementation in automated systems: Complex and challenging.

  • Susceptibility to errors: Increases with plugging and joining processes

Adhesive saving 50%


Effect on costs and CO₂ equivalents


Folding instead of gluing:

  • 10% more cardboard = 13.8 kg CO₂e/t against 2.52 kg CO₂e

  • 20% more cardboard = 27.6 kg CO₂e/t against 2.52 kg CO₂e

CO₂ - Footprint

Hotmelt

  • 2,5 kg CO₂e / kg

 

Energy

  • 0,434 kg  CO₂e / KWh

 

Adhesive Price:

  • 3€/kg hotmelt

 

Hotmelt System Usage

  • 200 days/year

  • 2-Shifts

 

Adhesive Consumption

  • Variable in steps between 1kg/h to 6kg/h

Hot melt consumption

Its role and impact on climate change

  • Based on our model and the staggered adhesive consumption

  • The table illustrates the CO₂ emissions resulting from the hot melt application process.
