A method for manufacturing a rectangular-bottomed packaging bag includes an unfolding step of unfolding a flat bag by separating a pair of opening/closing plates (13) inserted into the flat bag from each other in a thickness direction of the flat bag, and a gusset forming step, after the unfolding step, of forming a side gusset and a bottom gusset by thrusting folding plates (11 and 12) between the pair of opening/closing plates (13) from the outside of the bag toward the inside of the bag.

An insulating device can include a body assembly and a lid assembly where an insulating layer and aerogel structure is connected to both the body assembly and the lid assembly. An aperture with a closure is formed between the body assembly and lid assembly to form a storage compartment. The insulating layer and aerogel structure on the lid assembly may extend beyond the closure when the closure is sealed. The insulating layer and aerogel structure on the lid assembly may have an insulating ring and aerogel ring structure that has an increased thickness around its perimeter.

The invention relates to a process (100) for manufacturing an object (1) made of thermoplastic polymer composite from at least two parts (10) made of thermoplastic polymer composite, said thermoplastic polymer composite comprising a fibrous reinforcement and a thermoplastic polymer matrix, said process comprising the steps of: arranging (120) the two parts (10) made of thermoplastic polymer composite adjacently or overlapping at an assembly interface zone (11), and heating (130) to melt the thermoplastic polymer matrix at said assembly interface zone (11), so as to form an object (1) made of thermoplastic polymer composite comprising a welded interface (12).
