In side seam bonding on Hauni PROTOS-M8 cigarette makers running at 12,000–14,000 rods/min, the adhesive film is transferred from a laser-engraved ceramic anilox roller onto a 20–25 µm thick cigarette paper edge within a nip clearance of 15–25 µm. Under these conditions, the emulsion undergoes shear rates exceeding 10⁶ s⁻¹, requiring a low-shear viscosity of 600–800 mPa·s (Brookfield DV-II+, spindle #3, 20 rpm, 22°C) and a high-shear viscosity below 50 mPa·s to avoid misting and inadequate transfer. JZ-I low-viscosity VAE emulsion, compounded at 78–82 wt% with a hydrogenated rosin ester dispersion (8–10 wt%), triacetin plasticiser (4–5 wt%), and a benzisothiazolinone biocide (0.05 wt%), yields a rheology profile characterised by a power-law index n ≈ 0.65 and a yield stress of 2.8 Pa, as determined by Anton Paar MCR 302 oscillatory stress sweep at 1 Hz. This ensures consistent pick-up on the gravure cells and immediate transfer to the paper substrate, even when the roller temperature fluctuates between 32°C and 38°C due to frictional heating. The wet adhesive weight is controlled at 3.2–4.5 mg per cigarette; excess will cause seam burning delays and visible scorch lines during smoking, while under-application below 2.8 mg results in burst seams under thermal stress, as verified by the CORESTA Recommended Method No. 87 burst tension test (acceptance threshold: ≥11.5 N). The side seam must maintain integrity through the burn line to avoid fiddly formation of a non-conical coal, a defect monitored by automated optical inspection systems on the maker. Compliance is established under U.S. FDA 21 CFR 175.105 for indirect food contact adhesives and the German TabakerzV Annex 2 positive list; residual vinyl acetate monomer is routinely below 50 mg/kg as analysed by headspace GC per modified BfR XXXVI/1 conditions. The finished article is a standard king-size cigarette with a sealed longitudinal seam.
Filter rod seam bonding on a Hauni KDF-5 filter maker operating at 500 m/min delivers a cellulose acetate tow band that has been plasticised with 6–8 wt% triacetin (of tow weight). The seam adhesive is applied to the inner edge of the plug wrap paper just ahead of the forming horn. A critical failure mode arises when the plasticizer migrates from the tow into the adhesive layer, causing post-production softening and seam slippage during subsequent cutting and feeding. JZ-I emulsion is formulated at 84–89 wt% with a styrene-acrylic copolymer dispersion (5–8 wt%), a zinc ammonium carbonate crosslinking agent (0.15–0.25 wt%, added as a 10% solution), and defoamer. The crosslinking reaction proceeds during the drying zone at 130–160°C, yielding a film with a glass transition temperature (Tg) increased from 5°C to 28°C (DMA, 1 Hz, 3°C/min) and a triacetin uptake of less than 3 wt% after 7 days at 40°C, measured by weight gain on free films per modified ASTM D570-22. Application weight is 2.5–3.8 g/m² (dry), sustained by a siphon-fed needle nozzle with an orifice of 0.20 mm; any deviation above 4.2 g/m² can cause excessive wet-out that blocks paper porosity, compromising the filter ventilation required for ISO tar assays. Compliance references BfR Recommendation XIV (plastics in contact with dry foodstuffs), applied here to plasticiser-containing tow, and the adhesive must not contain substances listed in the European Food Safety Authority (EFSA) candidate list for tobacco product additives. The resulting continuous filter rod is cut into 108 mm six-up segments and later combined with tobacco rods.

The assembly of a filter cigarette in the Hauni MAX-S tipping unit involves wrapping a 22–26 mm wide tipping paper strip around the junction of a tobacco rod and a pre-cut filter segment, with the adhesive applied as a 2–4 mm wide bead along the inner edge. Line speeds of 650–750 m/min reduce the bead open time to 0.08–0.15 seconds before it contacts the tobacco rod surface, necessitating a wet tack that instantaneously exceeds 80 g/cm (modified FINAT FTM-9 probe test with cigarette paper). JZ-I low-viscosity emulsion is blended at 68–74 wt% with a low-viscosity partially hydrolysed polyvinyl alcohol solution (8–11 wt% of 88–92% hydrolysis degree, providing high hydrogen-bonding capacity) and a food-grade sucrose acetate isobutyrate plasticiser (1.5–2.5 wt%). This combination avoids surfactants that could lower dynamic surface tension below 42 mN/m and cause feathering on low-Cobb cigarette papers. The tack development curve, monitored on a proprietary drum tack simulator at 25°C/50% RH, shows a peak of 120 g/cm within 0.1 s and a maintenance above 60 g/cm for 0.5 s. Organoleptic neutrality is verified by the Council of Europe Resolution AP (2005) 2 protocol for mouth contact materials, with sensory evaluation against a control panel and permissible total non-volatile migration below 10 mg/dm² in a DIN V 53160-1:2002 saliva simulant at 37°C/24 h. The final pressure belt applies 1.2–1.6 bar to consolidate the bond before the rotary cutting drum separates individual cigarettes. Tipping adhesive films must also resist heat dissipation from the burn line; thermo-mechanical analysis (TMA) on cured films indicates no softening below 85°C. Conformity to EU Tobacco Products Directive 2014/40/EU Article 5 regarding non-aversive non-addictive additives is supported by the absence of prohibited substances in the polymerisation recipe. The finished output is an assembled filter cigarette with a mechanically sound, tasteless joint.
Soft pack cigarette inner liners consisting of 6.35–7.0 µm aluminium foil bonded to 32–38 g/m² unbleached kraft paper are produced on combi-laminators running at 250–350 m/min. The adhesive is applied via reverse gravure at a line pressure of 1.5–2.2 bar onto the aluminium foil, dried in a 18-metre recirculating hot-air oven with a peak temperature of 145°C, and immediately laminated to the paper under a heated pressure roller at 90–110°C. JZ-I emulsion is compounded at 52–58 dry wt% with a carboxylated styrene-butadiene latex (28–33 dry wt%, providing film elongation above 400%) and a mineral oil-free defoamer; the mixture exhibits a Brookfield viscosity of 150–300 mPa·s at 25°C to ensure smooth gravure pick-up and avoid ribbing on the applicator roll. Target dry coat weight is 4.5–6.0 g/m²; a lower weight under 3.5 g/m² leads to micro-cracking of the foil layer during subsequent embossing on a G.D Packmatic line operating at 200–220°C flat dies. Laminates are tested for heat-seal integrity after 0.5 s dwell at 130°C and 2 bar pressure, achieving a T-peel strength ≥220 g/15 mm per ASTM F904-98 and folding endurance at ≥1,000 cycles under ISO 5626:1993. Compliance for materials in indirect contact with tobacco is covered under U.S. FDA 21 CFR 176.170 and BfR Recommendation XXXVI (paper and board for food contact), with specific migration limits for formaldehyde and metaldehyde set at nondetectable levels using LOD 0.5 µg/dm². The final laminated liner reels are slit and palletised for supply to cigarette packaging machines.
Carton closing on BDT/Körber and Bradman Lake race-track gummers at 140–180 packs/min applies a fine line of adhesive to the dust flaps and side seams of folding cartons. JZ-I emulsion is fed directly from a 200 litre IBC to the pump-fed nozzles without additional dilution, representing 92–95 wt% of the as-used product; the remaining fraction is an isothiazolinone preservative system. Viscosity at the nozzle is maintained at 800 ±150 mPa·s (Brookfield #4, 20 rpm) to prevent dripping during idle stops while ensuring consistent nozzle cut-off. The adhesive forms a wet bond weight of 9–12 g/m² and must yield fibre tear (> 95% fibre) on 280–320 g/m² solid bleached sulphate within <2 seconds of compression, verified by the TAPPI T 456 procedure at 23°C/50% RH. Compliance: 21 CFR 176.170 and EN 12960:2001 for packaging adhesives; no volatile organic solvents or plasticisers are present. The output is a sealed carton of 200 cigarettes ready for overwrapping.
