The present disclosure relates to a package for valuable products. The package comprises: a support base having a supporting surface for a product to be supported; a hollow body that has an open portion for the insertion of the product to be supported. The hollow body is engageable to the support base along a relative movement direction perpendicular to the supporting surface. The package further comprises an opening mechanism interposed between the support base and the hollow body and switchable between a closing condition, wherein the hollow body is in contact with the support base or is placed close to the latter, and an opening condition, wherein the hollow body is spaced from the support base so as to allow the access to the product resting on the latter. The switching of the opening mechanism between the closing condition and the opening condition is operated by actuating a control element along a control direction transverse to the relative movement direction between the hollow body and the support base.

A shipping system for shipping planar substrates includes a plurality of planar substrates stacked to form a pack and a plurality of interleaving material including substantially spherical beads positioned between the substrates of the pack and configured to carry a load. Substantially all of the beads have a diameter within 25% of D.sub.max, where D.sub.max is a diameter corresponding to a size of an opening of an upper limit sieve used in the shipping system. Also disclosed are a spacer for use in a shipping system for shipping planar substrates, a wrapped system for shipping planar substrates, a method of wrapping a system for shipping planar substrates, and a powder applicator.

A multi-layer foam sheet with an apparent density of 30 to 300 kg/m.sup.3 and a thickness of 0.05 to 2 mm, including a foam layer containing a polyethylene-based resin, and an antistatic layer fusion-laminated by coextrusion on each of both sides of the foam layer. The antistatic layer has a basis weight of 1 to 10 g/m.sup.2 and contains a polyethylene-based resin, a polystyrene-based resin, a styrenic elastomer, and a polymeric antistatic agent, with the polystyrene-based resin being contained in the antistatic layer in an amount of 15 to 70% by weight.

Provided is a glass plate interleaving paper including cellulose pulp as a main component. A percentage of aluminum content is below 0.2 mass %, and a basis weight is in a range from 10 to 100 g/m.sup.2. Further, it is preferred that the glass plate interleaving paper have a percentage of aluminum content below 0.01 mass %. Still further, it is preferred that the glass plate interleaving paper have a percentage of talc content below 0.1 mass %.

The present invention relates to a spring assembly, including: a coil spring having an inner space formed by the spring windings thereof; and an anti-entanglement element for protection against entanglement of the spring assembly, in particular with at least one further spring assembly or with at least one other coil spring; wherein the anti-entanglement element is partially disposed in the inner space formed by the spring windings and extends longitudinally through at least a portion of the inner space; and wherein the anti-entanglement element (14, 26) is provided in the form of an anti-entanglement stirrup, formed separately from the coil spring and clampingly supported in the inner space; or wherein the anti-entanglement element is provided in the form of an anti-entanglement pin, which is formed separately from the coil spring and has a front loss-prevention or captive end and a rear stop end.
