Abstract
Described are liners for bulk containers that are abuse resistant. The liners include at least one sidewall. The sidewall includes at least an exterior ply and an interior ply. Optionally, the sidewall may include at least one intermediate ply. One of the plies includes a first polyolefin-silicone copolymer. The adhesion between the plies is from 0 g/2.54 cm to 50 g/2.54 cm (0 g/in to 50 g/in).
Claims16
A liner for a bulk container, the liner comprising:
- at least one sidewall comprising at least an exterior ply, an interior ply and optionally, at least one intermediate ply;
- and
- wherein at least one of the plies comprises a first polyolefin-silicone copolymer, wherein the adhesion between the plies of the first sidewall is from 0 g/2.54 cm to 50 g/2.54 cm (0 g/in to 50 g/in), and wherein the liner comprises a flex crack failure time of greater than 125 minutes when measured according to ASTM D 999-08, Method A2, free of dunnage, and with the liner being filled with water having a water weight of 1.089 kg (2,400 lb).
A liner for a bulk container, the liner comprising:
- a first sidewall comprising at least an exterior ply and an interior ply;
- a second sidewall comprising at least an exterior ply and an interior ply;
- optionally, at least one first sidewall intermediate ply positioned between the first sidewall exterior ply and the interior ply;
- and
- optionally, at least one second sidewall intermediate ply positioned between the second sidewall exterior ply and the interior ply;
- wherein the first sidewall exterior ply comprises a first polyolefin-silicone copolymer comprising a first linear low density polyethylene, wherein the second sidewall exterior ply comprises a second polyolefin-silicone copolymer comprising a second linear low density polyethylene, wherein the adhesion between the plies of each the first sidewall and the second sidewall is from 0 g/2.54 cm to 50 g/2.54 cm (0 g/in to 50 g/in), and wherein the liner comprises a flex crack failure time of greater than 125 minutes when measured according to ASTM D 999-08, Method A2, free of dunnage, and with the liner being filled with water having a water weight of 1,089 kg (2,400 lb).
