Natural rubber

At monta we focus on the manufacturing and processing of natural rubber adhesives that are coated on PVC, BOPP/MOPP, paper and PET carrier materials. Natural rubber adhesives are versatile in use and ensure durable sealing of cardboard packaging even on critical surfaces such as recycled carton and under extreme conditions. 


  • high temperature resistance
  • high shear strength
  • broad field of use


In order to complete our product range we also offer pressure sensitive tapes that are coated with hotmelt adhesive. In the production process synthetic rubber - in granular form - is melted and applied to the backing while it is hot.


  • high adhesive strength on steel
  • high transparency
  • good immediate tack


In order to further complete our product range we also offer self-adhesive packaging tapes that are coated with Acrylic adhesives. There are two different types: water based Acrylic adhesives, which dominate the market, and solvent based Acrylic adhesives. The raw material supplier prefabricates the dispersion Acrylic adhesive to be coated mainly on BOPP substrate. It can not be changed in its composition. 


  • high transparency
  • good UV resistance
  • good aging resistance



For the manufacturing of our PVC adhesive tapes we use monoaxially oriented rigid PVC films. PVC is the abbreviation of Polyvinylchlorid. This backing is free of softeners and available in transparent, flat and embossed versions as well as in different colors. At monta we process film thicknesses from 30μ to 60μ. 


  • very robust
  • perfectly printable
  • low noise and smooth unwinding properties
  • low elongation


There are two kinds of Polypropylen foils 

biaxially oriented Polypropylen films (BOPP)


monoaxially oriented Polypropylen films (MOPP)

BOPP substrates are mainly used for manufacturing classical pressure sensitive tapes, if a solid price/performance ration is paramount. At monta we process film thicknesses from 25μ to 50μ.


  • works perfectly with all adhesive systems
  • noisy or silent unwinding is possible 
  • high tensile strength in longitudinal and cross direction
  • high temperature resistance 

MOPP backings are mainly used for manufacturing special tapes, if high stability is paramount. At monta we process film thicknesses from 55μ to 110μ.


  • low elongation
  • high longitudinal tensile strength 
  • high temperature resistance


Backings that are based on paper are a good alternative to plastic based foils. The paper is impregnated and thus humidity-resistant and weatherproof. At monta we process paper with a weight of 60g/sqm. 


  • silicone-free
  • plastic free
  • good printability
  • ecologically beneficial


PET is an abbreviation of Polyethylentherephthalat, better known as Polyester. This backing is biaxally oriented and used for manufacturing special tapes, if high tensile strength is paramount. At monta we process film thicknesses from 23μ to 50μ.


  • high performance substrate
  • low elongation
  • high temperature resistance


PLA is an acronym for polylactic acid and is a biobased plastic material, made from plant based starch. It is derived from maize that is grown for industrial purposes, on soil that is unsuitable for growing food.

The PLA film that is used for the production of monta biopack® is compostable in industrial conditions and has been awarded the OK COMPOST INDUSTRIAL mark by TÜV Austria.


  • Strong and robust backing material
  • Low elongation
  • Tearable by hand
  • Compostable (industrial) and suitable for recycling


Essentials for optimal carton sealing

Adhesion Strength

Peel adhesion has to be evaluated in combination with immediate tack (quickstick) and shear adhesion measured on 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 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 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. 


The quality of our self-adhesive packaging tapes is thoroughly tested in our own laboratory, following the guidelines of internationally approved test methods. We have also developed special practical trials. In order to provide full documentation we work with reference numbers that enable us to trace the finished product down to its raw materials. Our most important tests:


Measured is the so called "adhesion value on steel", the force required to remove an adhesive tape with a specific width under defined conditions (unwinding-angle, pressure, speed) from a standard metal surface.


A test method called "rolling ball" defines the tack (immediate adhesion) of an adhesive tape. Measured is the distance in centimeter that a ball rolls on the adhesive side of the tape before it remains stuck.


Shear strength indicates how long an adhesive tape sticks to a cardboard surface when weighed down vertically by a defined force. The longer the tape sticks, the higher its shear strength. Thus you can see that for example natural rubber adhesive shows a higher shear strength than Hotmelt or acrylic adhesives.


This test was developed over 30 years ago. It is an inherent part of the monta verification process: the adhesive tape is applied to a recycling cardboard that is put under extreme tension. The test shows if the tape can be sheared off or if the cardboard will open. The test takes place in a heated room under extreme conditions.


When applying self-adhesive tapes on a carton, always put focus on a steady application pressure. If the application pressure is not firm enough, the tape lifts itself from the carton surface and the carton opens.
When applied with a tape dispenser, please make sure that the track is close to the carton to fix the tape with the pressure flap along the total length of the carton and the front sides.
When a carton closing machine is used, the tape is automatically applied with steady pressure.

In order to avoid damage to the roll, please do not open carton or plastic shrink with sharp or pointed objects. Our boxes do have a so called push-and-pull perforation, so the cartons can be opened easily.
Generally it is important that both adhesive tape and carton are stored at room temperature.  



Self-adhesive packaging tapes can only be stored for a limited period of time due to their characteristics and chemical composition. High temperatures in summer and sub-zero temperatures in winter influence the tape even in closed cartons. Inappropriate storage exerts influence on the product characteristics: the roll of adhesive tape changes its shape and the properties of the adhesive change. The adhesive embrittles and comes loose. For optimal handling and processing, we recommend storing the self-adhesive tapes in the original packaging in a dry and dark place and between 15°C and 25°C. This way the tape keeps its original characteristics and can be used without problems.
