A glass tube for pharmaceutical containers is provided. The tube has an inner surface at an inner diameter, an outer surface with an outer diameter, a first end defining a first closed end, a second end defining a first closed end, a first location 400 mm from the first end, a first intermediate location 15 mm from the first end, and a ventilation hole at a first vicinity. The first vicinity is between the first intermediate location and the first location. The glass tube can have a ratio of an integrated Na.sub.2F.sup.+ signal to an integrated .sup.30Si.sup.+ signal of at least 0.10, where the integrated Na.sub.2F.sup.+ signal and the integrated .sup.30Si.sup.+ signal are integrated over a depth of 100 nm. The glass tube can have a ratio between a fluorescence emission determined at a first vicinity and a fluorescence emission determined at a middle section of at least 0.6.

Envelopes include one or more walls defining an envelope pocket configured to hold an item. The envelope also can include a closure seal configured to maintain the envelope pocket in a closed state once the item has been placed therein. At least one of the walls can be formed from an extensible paper having the ability to stretch, within limits, without tearing.

A pouch includes a packaging material. The packaging material includes a first film composed of machine direction oriented polyethylene oriented in a machine direction corresponding to a direction orthogonal to an up-down direction of a pouch and a second film laminated on the first film. The second film has tensile breaking stress in a transverse direction corresponding to the up-down direction of the pouch of 50 MPa or more.
