Definitions
- the invention relates to an aqueous adhesive with enzymatically degraded starch and its production and use in the cigarette industry.
- Natural raw materials are increasingly being used to glue cigarettes.
- adhesive mixtures based on gelatin are described.
- such adhesives do not meet all the requirements which are to be placed on an adhesive for mechanical longitudinal seam gluing using glue disc and nozzle application systems customary in the cigarette industry. In terms of their structure, they lie between aqueous systems and hotmelt adhesives and must be applied to the paper areas to be bonded from heated apparatuses.
- all adhesives based on animal proteins there is a risk of decomposition and the development of unpleasant odors when heated.
- EP 0368136 B1 describes the use of adhesive mixtures containing gum arabic for the longitudinal seam gluing of cigarette tubes. These adhesive mixtures contain 40 to 120 parts by weight of gum arabic, 3 to 80 parts by weight of water-soluble starch degradation products and / or carboxymethyl starch and / or gelatinized starch and, if appropriate, conventional preservatives in aqueous solution with a viscosity of per 100 parts by weight of water Brookfield 1000 to 15000 mPas at 20 ° C.
- the water-soluble starch degradation products to be used according to the invention include oxidatively or hydrolytically, for example, enzymatically degraded starches and dextrins. Disadvantages of these adhesives are the uneven seam width, deposits on the nozzle and threading of the adhesive on the nozzle.
- the object of the invention is to ensure a safe and permanent gluing of longitudinal seams of cigarette tubes with the machines customary in the cigarette industry, in particular taking into account the high production speeds of 10,000 cigarettes per minute required there using nozzle application systems for longitudinal seam bonding and using roller application systems for filter bonding.
- the disadvantages mentioned above should be avoided.
- the invention can be found in the claims. It essentially consists of an aqueous adhesive with enzymatically degraded starch, with no other substance having a larger proportion by weight of the solids content.
- the proportion of the enzymatically degraded starch is preferably greatest.
- the solids content is determined in accordance with DIN 53189 (drying at 105 ° C. to constant weight).
- binders may also be present, for example native starch, substituted starch and cellulose derivatives.
- Mixtures of enzymatically degraded starch with undegraded starch allow higher machine speeds with very good adhesive results.
- the mixing ratio of degraded to undegraded starch should advantageously be 1: 1 1, preferably 1: 0.5 to 0.1. Mixtures outside this range are possible, but they have disadvantages in at least one respect.
- the adhesive may also contain additives to achieve certain properties, in particular preservatives.
- Suitable preservatives are the agents customary in the adhesive and tobacco industry according to the German tobacco regulation, in particular potassium sorbate and / or p-hydroxybenzoic acid ester.
- the enzymatically degraded starch has the largest share, in particular its share is above 50% by weight, based on the binding component. It is preferably used as the sole binder.
- the adhesive according to the invention there are up to 100 parts by weight of binder, preferably 5 to 80 parts by weight, per 100 parts by weight of water.
- Starch degradation products are particularly suitable for the invention, in which predominantly the -1,4 bond has been split and less the -1,6 bond or the ⁇ -1,3 bond.
- the starch should have been broken down with the ⁇ -1,4-glucan-glucohydrolase, preferably with an ⁇ -At ⁇ ylase, namely a fungal-oc-amylase.
- Starting products for the degraded starch products are preferably chemically unmodified food starches such as Waxy corn, potato, tapioca and wheat starch.
- chemically modified starches can also be used if they consist of only one component, for example acetylated distarch adipate or N-octenyl succinate.
- the enzymatic degradation is generally carried out under the following conditions:
- the reaction temperature is 30 to 60 ° C, especially 45 to 55 ° C.
- the pH is 4 to 8, in particular 5 to 7.
- the enzyme is added in an amount of 1 to 300 ppm, in particular 10 to 30 ppm, based on the starch to be broken down.
- the starch starting product is used in an amount of 10 to 70, in particular 25 to 40,% by weight, based on the aqueous system.
- the enzymatic degradation is continued until the viscosity of 1000 to 20,000 mPa-s, in particular up to 2,000 to 6,000 mPa * s according to Brookfield.
- the enzymatic breakdown generally takes 5 minutes to 24 hours, in particular 10 to 60 minutes.
- the enzyme is thermally denatured.
- the reaction mixture obtained is now made up into the adhesive according to the invention, in which case a further binder component is added, if this has not already been done before the reaction.
- the additives are now added, especially the preservative.
- the viscosity of the adhesive according to the invention is adapted to the type of application and the machines used.
- the viscosity should be in the range from 1000 to 20,000, in particular 2,000 to 6000 Pas are measured according to Brookfield at 23 ° C (RVT) (ISO 2555).
- the adhesives according to the invention can be used in a variety of ways, in particular to bond paper to one another. Above all, however, they are suitable for the manufacture of cigarettes, especially for gluing the longitudinal seam and filtering life. It is of particular importance that the adhesives according to the invention can be used on conventional machines in the cigarette industry.
- the adhesive mixtures according to the invention are applied in conventional cigarette manufacturing machines via nozzles to the longitudinal seam regions of the cigarette cases to be glued and result in effective gluing.
- the adhesive mixtures are usually applied at ambient temperature. In the case of highly viscous adhesives, however, slight heating may be necessary. In most cases, however, it is sufficient if only the application nozzles are heated. It is also possible to use the adhesive according to the invention on the roller application systems for filter adhesion. It is particularly important that speeds of up to 10,000 cigarettes per minute are made possible with a single-lane driving style.
- the adhesives according to the invention have the following advantages: more uniform seam width, less deposits on the nozzle, no stringing and higher strength.
- the invention will now be described in detail using an example:
- the adhesive mixtures mentioned above were tested in a commercially available cigarette machine from Hauni.
- the gluing nozzles were conventional nozzles with a heated head.
- the bonding was carried out under the following conditions: Protos 90 S machine, 1.6 mm nozzle with pump, heating approx. 300 to 320 ° C., cigarette brand R6 (100 mm), speed 6000 cigarettes per minute.
- no contamination was noted in the format chamber.
- the longitudinal seams had excellent adhesive strength.
- the seam width was uniform, as shown by the staining with an iodine solution. When the seams were forcibly separated, the adhesive areas became matted, indicating strength close to the material breakage.
