Described is a mono-axially oriented polyolefin film including a core or base layer containing a plurality of voids formed by a cavitating agent, wherein the film is oriented at least 4 times in the machine direction, and exhibits excellent tear resistance in the transverse direction.

An insulation sheet forming apparatus that forms an insulation sheet having one or more bent regions includes an unwinding module; a preforming module configured to form a preforming region on the insulation sheet supplied from the unwinding module; and a bending module configured to form the bent region on the insulation sheet by bending the insulation sheet supplied from the preforming module, in which the preforming module has a width which is adjustable in a width direction that intersects a movement direction of the insulation sheet.

A method for manufacturing an external component for watches or jewellery, especially a bracelet, includes the steps of: providing a substrate including a first face opposite to a second face and co-extrusion coating the first face and the second face of the substrate respectively with a first and a second band of synthetic material. The first band forms on the first face a transparent or translucent layer so that all or part of the substrate remains visible.

In an embodiment, a slit film tape composition includes a propylene-based elastomer comprising 1-16 wt % ethylene based on a total weight of the propylene-based elastomer, the propylene-based elastomer having a melt flow rate (MFR) of 1-50 g/10 min; a polypropylene comprising 10-100 mol % propylene based on a total weight of the polypropylene, the polypropylene having a MFR of 2-35 g/10 min; and a filler. In another embodiment, a slit film tape composition includes a propylene-based elastomer comprising from 5-30 wt % ethylene based on a total weight of the propylene-based elastomer, the propylene-based elastomer having a MFR of 35-60 g/10 min; a polypropylene comprising 10-100 mol % propylene based on a total weight of the polypropylene, the polypropylene having a MFR of 2-35 g/10 min; and a filler.

The invention relates to a process for the production of a non-fibrous drawn polymer tape, said process comprising the steps: a) compacting a polymer powder in a press to form a compacted polymer bed; b) calendering said compacted polymer bed to form an oriented polymer tape; and c) drawing said oriented polymer tape to form a highly oriented polymer tape; characterized in that step a) comprises compacting the polymer powder at a temperature and pressure such that from 0.1 to 20 wt. % of the polymer powder as measured by DSC is melted. The invention also relates to a tape obtainable by the above process, and a monolayer, multilayered material sheet and ballistic resistant article comprising such a tape.

Backing films for adhesive tapes are presented, as well as adhesive tapes comprising such backing films, which may include tapes used in construction such as seam sealing tapes, roofing tapes, and flashing tapes. The backing film comprises a core layer, a first skin layer, and optionally a second skin layer, where the backing film has a coefficient of thermal expansion of less than 0.500 measured in at least one direction within the plane of the film, and, in some embodiments, a Young's modulus of less than 550 MPa as measured in at least one direction. In some embodiments, the backing film has a coefficient of thermal expansion of not more than 0.510 and a Young's modulus of not more than 540 MPa as measured in any direction within the plane of the film. In some embodiments, the core layer comprises a polyolefin, and skin layers comprise a thermoplastic elastomer.

A member for an image forming apparatus includes a surface layer including a block copolymer, wherein the block copolymer includes a polyamide block and a polyether block and the composition ratio of the polyether block to the polyamide block is from 0.2 to 1.5.

Woven irrigation tubing comprises a woven, extrusion coated & laminated tube formed of a high density polyethylene (HDPE) outer layer, a low density polyethylene (LDPE) middle layer and a linear low density polyethylene (LLDPE) inner layer. The finished tubing is treated for ultraviolet resistance. The tubing is tied off at a distal end with a proximal end connected to a pressurized irrigation source. Watering holes are created in the tubing at spaced intervals and the resulting water streams are directed into parallel plowed furrows. The tubing is completely recyclable. The tubing is formed by manufacturing tape for the woven outer tubing cover, stretching the tape along its length to strengthen it, weaving the outer layer from the tape, flattening the woven outer layer, extrusion coating each surface of the outer layer with LDPE, laminating the LLDPE inner layer to the LDPE, reversing and winding the tubing for storage and distribution.

There is herein described a range of sporting products comprising sucker elements, which can be used in various uses such as on products which require, for example, hand or any other type of grip contact. The grip contact may be with the feet or hands (or any other part of the body). The sporting products that the grips may be used on may comprise rackets (e.g. for tennis/badminton/squash etc.), bats (e.g. cricket/baseball/table-tennis etc.), bicycles, motorcycles, golf clubs, water sports (surfing, windsurfing) etc. The sucker elements may also be included with other sporting product such as on the inside and/or outside of running sock or shoes for example. There is also described a range of industrial products comprising sucker elements which can be used in a range of applications such as on a range of vehicle parts (e.g. bus rails, train rails, boat rails, steering wheels, motorbike handles and foot pegs etc.), industrial machinery (e.g. handles for tools such as drills, pneumatic drills etc.), flooring (e.g. decking on boats and in industrial environments), crockery, bathroom and shower flooring, and surfaces to aid disabled people.
