A hot-melt adhesive composition is disclosed. The hot melt adhesive comprises

Hot melt adhesive for polyolefin films

The invention relates to hot melt adhesives which are pressure sensitive adhesives whereby the adhesive is provided in a granulated form and is free-flowing and does not block during storage. Such pellets can be used as feed for automated feeder devices for the supply hot melt application systems.

Free-flowing pressure sensitive adhesives

The invention relates to a nontacky film-forming polymer composition (cover material), and tacky hot melt adhesives in the form of pellets which are coated with the polymer composition and producible by coextruding the hot melt adhesive and the cover material. The film-forming composition comprises 5 to 40% by weight of at least one Fischer-Tropsch wax having a melting point of &#x3e;95&#xb0; C. and 30 to 70% by weight of at least one metallocene-catalyzed polyolefin having a softening point of &#x3e;95&#xb0; C. and a melt flow index (MFI) (230&#xb0; C., 2.16 kg) of &#x2264;1000 and &#x2265;300 g/10 minutes. The invention further relates to suitable uses for such hot melt adhesives, methods for their use, and products containing these adhesives.

Covering materials for adhesive hot-melt glues

The invention relates to a hotmelt adhesive comprising 10 to 40 wt % of at least one branched styrene-isoprene-styrene block copolymer having a weight percentage diblock fraction in the polymer of less than 30% and a melt flow index of less than 5 g/10 minutes at 200&#xb0; C. under a test load of 5 kg; 0 to 40 wt % of at least one styrene polymer or styrene copolymer; 20 to 60 wt % of at least one tackifying resin; 0 to 15 wt % of at least one plasticizer; and 0 to 16 wt % of additives and auxiliaries selected from stabilizers, adhesion promoters, fillers or pigments, waxes and/or other polymers. Also included are the use thereof to bond films, and products, especially packaging products, that include this adhesive.

Extrudable hotmelt adhesives based on branched SIS polymers

The invention relates to storage-stable hot-melt adhesive containing 15 to 70 wt % of a mixture of at least one copolymer based on ethylene and/or propylene and at least one C4 to C20 &#x3b1;-olefin which is obtainable as a block copolymer by metallocene-catalyzed polymerization, and at least one styrene block copolymer, 10 to 70 wt % of at least one tackifying resin, 0 to 40 wt % of further additives, wherein the total of the percentages should amount to 100% and the tackifying resin is entirely or in part a soft resin.

PSA containing olefin block copolymers and styrene block copolymers

Melt adhesive containing 5 to 40 wt.-% of at least one ethylene-based copolymer and at least one Cto C-&#x3b1;-olefin obtained through metallocene-catalyzed polymerization, 10 to 65 wt.-% of at least one tackifying resin, 0 to 35 wt.-% of a plasticizer, 0.01 to 30 wt.-% additives and additional ingredients selected from stabilizers, adhesion promoters, fillers or pigments, waxes and/or other polymers, wherein the total should amount to 100%, characterized in that copolymer A is a block copolymer that exhibits a substantially even elastic behavior in the range of 0&#xb0; C. to 25&#xb0; C., measured as the ratio of the storage modulus E' according to (E&#x2032;&#x2212;E&#x2032;)/E&#x2032;&#x3c;1.5.

Melt adhesive based on metallocene catalyzed olefin-&#x3b1;-olefin copolymers

Adhesive systems are useful for bonding wrap-around labels using an overlap adhesive in their application to blown plastic containers, more particularly plastic bottles. The adhesive system includes reactive contact adhesives based on multifunctional macromonomer compounds curable in steps by different reaction mechanisms, which may also be present mixed with one-stage reactive mixture components.

Use of selected adhesive mixtures for overlap adhesion of round labels when applied to plastic bottles

Adhesive system for sticking all-round labels
