The present invention refers to a process for making a calcium carbonate containing material, wherein the process includes a specific drying procedure and allows for the provision of calcium carbonate materials with reduced moisture pick-up and low porosity.

The disclosed invention describes a novel approach to the utilization of the fine mineral matter derived from coal and/or coal refuse (a by-product of coal refining) to convert a non-biodegradable plastic into a biodegradable plastic. The fine mineral matter could also be based on volcanic basalt, glacial rock dust deposits, iron potassium silicate and other sea shore mined deposits. The conversion of the non-biodegradable plastic into biodegradable plastic in soil further increases nutrients availability in soil with the transition metals released as a result of biodegradation of the biodegradable plastic.

A thermoplastic product, such as a film, tubing, sheeting, and a profile with a cross-section, is made by a process including extruding a melt-blended mixture comprising a thermoplastic polymer and a fluorocarbon additive through an extruding die. The thermoplastic polymer and the fluorocarbon additive are substantially homogenously distributed in the melt-blended mixture before extrusion. Upon cooling, the extruded product forms into a solid thermoplastic product comprising the thermoplastic polymer and the fluorocarbon additive and having a particular shape. The fluorocarbon additive has a lower surface energy than that of the thermoplastic polymer. As a result, a concentration of the fluorocarbon additive through a cross-section of the solid thermoplastic product is lower in the interior thereof and higher at the surfaces thereof. The solid thermoplastic product has a lubricity surface. The thermoplastic product having lubricity surfaces may be further flexible and/or elastic, or non flexible.

A method for producing a polymer latex, includes a step of emulsifying a polymer solution of a synthetic polyisoprene and/or a styrene-isoprene-styrene block copolymer, in water in the presence of a rosin and/or a rosin metal salt, thereby obtaining an emulsified liquid, wherein the rosin and/or the rosin metal salt to be used have/has a total content rate of abietic acid, neoabietic acid and palustric acid, and salts thereof, of 5% by weight or less.

A cycloolefin polymer (COP) bonding method wherein a first material that is COP and a second material that is COP or glass are bonded. The method includes: a step of exposing at least a bonding surface of the first material to H.sub.2O plasma; and a step of mating the bonding surface of the first material and a bonding surface of the second material. According to the method, the cycloolefin polymer (COP) can be bonded to a target material without applying high pressure or high temperature, and without affecting the optical properties.

A breathable, polyolefinic, filled, stretched film. The film has a water vapor transmission rate of at least 500 g/m.sup.2 in 24 h according to ASTM D6701-01. The water column of the film is more than 300 mm according to EDANA WSP 80.6. The film has an imprint which is bonded to the film via an adhesive. The film has at least one layer in which the adhesive is integrated.

A recyclable packaging film and a package is disclosed. The packaging film includes a first surface including a first polyolefin-based polymer. The packaging film further includes a second surface including a second polyolefin-based polymer. The packaging film further includes a heat-resistant coating attached to the first surface. The heat-resistant coating is coextensive with less than 50%, by area, of the first surface of the packaging film. The package includes the packaging film and a heat seal connecting the second surface of the packaging film to a third surface.

The invention relates to a for recycling fabric into plastic granule for plastic manufacturing processes, the method comprising the steps of: a) Collecting fabric comprising fabric fibers b) Pulverizing the fabric into a powder of fabric particles c) Pelletizing the powder with a binder such that fabric pellets comprising the powder of fabrics are formed d) Extruding a mixture of the fabric pellets and a plastic compound into plastic granule.

Methods for reducing moisture content of alkaline earth metal carbonate may include introducing alkaline earth metal carbonate having a moisture content ranging from about 0.1% by mass to about 10% by mass into a primary crusher and operating the primary crusher to obtain alkaline earth metal carbonate particles having a top cut particle size d.sub.90 of 90 microns or less. The method may also include introducing the particles into a primary grinder and operating the primary grinder to obtain reduced-size alkaline earth metal carbonate particles having a median particle size d.sub.50 of about 60 microns or less. The method may further include introducing the reduced-size particles into a classifier mill and operating the classifier mill to obtain further-reduced-size alkaline earth metal carbonate particles having a median particle size d.sub.50 of about 12 microns or less, and a moisture content of about 0.15% by mass or less.
