Alternative methods for sealing pouch materials, for example, using radio frequency (RF) sealing techniques, and oral pouched products formed according to those methods are provided. Some pouched products may include an outer water-permeable pouch defining a cavity having a composition situated in the cavity, wherein the outer water-permeable pouch comprises a fleece material, the fleece material comprising a plurality of fibers and an RF sealable material. In some embodiments, methods of RF sealing pouch materials may include providing one or more fleece materials having a RF sealable material and sealing the one or more fleece materials using radio frequency energy to form a RF sealed pouched product.

A splicable environmentally-friendly non-PVC advertising cloth made of a woven structure, wherein the advertising cloth comprising a mesh base layer (40); a first adhesion-promoting structural layer (10), which is a refractory and waterproof layer covering the front surface (43) and the rear surface (44) of the mesh base layer (40); a second adhesion-promoting structural layer (20) coated on the first surface (13) of the first adhesion-promoting structure layer (10); and a third adhesion-promoting structural layer (30) coated on the upper surface (24) of the second adhesion-promoting structure layer (20), therefore, waterproof and ink-absorbing structure arranged on a mesh base (40) layer, and the width of the advertising cloth (50) can be spliced unlimitedly as required by using high frequency splicing, making the environmentally friendly advertising cloth more applicable also improving the overall advertising effect and quality.

A tube seal apparatus including a sealing iron having a tube sealing end, an insulating shroud having a tube clamping end, wherein the sealing iron is at least partially disposed within the insulating shroud. The apparatus further includes an anvil having a cutting detail and a non-stick membrane disposed between the anvil and the tube clamping end of the insulating shroud. The sealing iron and insulating shroud are configured to advance towards a tube to be sealed positioned between the non-stick membrane and the anvil. The tube clamping end is configured to clamp the tube through the non-stick membrane. The sealing iron is configured to advance towards the tube to melt and seal the tube against the cutting detail through the non-stick membrane.
