Insulating packaging material is wrapped or otherwise positioned around the typically temperature sensitive product, with the packing material including, alternatively, 1 ply (FIG. 22; metallized plastic film), 2 ply (FIGS. 23 & 24) and 3 ply (FIG. 25) material, in which some of the 2 ply & 3 ply embodiments include a layer of bubble wrap material having its bubble side placed or laminated against the flat side of the adjacent ply, which adjacent ply can be, for example, a mettalized plastic film or a foam layer or both layers can be included. With such a bubble side arrangement, multitudinous air pockets are formed between the bubbles of the bubble wrap and the other ply's typically flat interfacing surface. A separate layer of bubble wrap also preferably is placed about the interior of the box with its bubble side placed against the interior flat surfaces of the box, with the bubbles forming air pockets with the flat sides, further enhancing the insulating properties of the packaging for the goods. An exemplary system for delivering perishable groceries (120 / 120'), including a corrugated cardboard or other type box (100); a source of cold (or heat as needed) maintaining the temperature inside the box within a desired temperature range for hours or days, using an all encompassing pouch of packet material (110 / 10), used individually (FIGS. 2 & 3) or collectively (FIGS. 5 & 6), with each packet (17) containing a super-absorbent polymer (14, FIG. 12) which is hydrated (14', FIG. 12A) and then either frozen (e.g., in a freezer) or heated (e.g., in a microwave), without producing moisture as the polymer returns to its natural state; a protective cover (130) protecting the box and its contents from heat radiation (e.g., sunlight).

A practice ammunition projectile has a projectile head with one or more sheets of plastic material, each having a plurality of frangible “bubble shaped” compartments containing liquid chemical components for optical and / or Infrared marking of a target upon impact. The sheets are preferably flexible sheets in the nature of a “bubble wrap” of the type used as padding for packaging. These so-called “matrix packages” are installed adjacent the inner surface of the shell forming the projectile head and provide stability when the compartments break up upon setback when the projectile is fired from a weapon.

The invention discloses a blown film edge trimming device, the structure of which comprises: an electric control box, a packaging horizontal tank, a blower, a blown film cutting door frame, a conveyor belt table, a bracket frame tripod, and the invention realizes the use of the packaging horizontal tank and The blown film is matched with the door frame, and the right side of the grid door frame and the alignment clip seat is blown and packaged by encapsulating the horizontal groove to form a smooth adjustment of the operation effect through a short distance of the trimming pressing frame, so that the edge strip density after edge trimming is effective Adjust the flatness by sliding and pressing the column plate and adjust the toughness of sliding and pressing and attaching tight pull to improve the integrity of the air-absorbing mechanical package after the blown centered film bulges, and the smooth anti-wrinkle adjustment of the film end surface The sliding pressure operation is formed by the sliding pressure guillotine, so that the air bubbles wrapped in the film are pressed out to ensure the smoothness and uniformity of the product after filming.

The invention discloses a fully automatic film and coil packaging integrated production process, which belongs to the field of film and coil packaging production. The multi-step process of wrapping, hot-melting, capping and fixing, turning and erecting, and palletizing is reduced and synchronized, and it can automatically adapt to film coils with different specifications and diameters or film coils with certain production deviations without stopping Calibration and adjustment, occupy less space, reduce equipment costs, greatly improve production efficiency, when faced with large quantities of film coils of different specifications and diameters, it has incomparable advantages of high efficiency and high production, especially for large-diameter films When coiled, it can be turned over and erected directly after being wrapped with a cover. The stability is extremely high, and it can be automatically adjusted according to different diameters. Compared with the existing mechanical arm or turning table, the safety has been improved.
