A tamper evident plastic bag having a sheet folded to form opposing first and second panels and a bottom gusset. The bag includes a first seam and a second seam that cooperate with the panels and the gusset to form a content receiving region between the panels. A third seam secures the first panel to the second panel at a location between the first seam and the second seam forming two compartments of the content receiving region. An adhesive strip is disposed on an internal surface of the first panel, and the strip being positioned opposite an opposing portion of an internal surface of the second panel. When a protective strip is removed, and the adhesive strip is brought into contact with the opposing internal surface of the second panel, a seal is formed that closes the plastic bag, forming a vent between the first seam and the seal.

A food bag assembly for providing a serving surface includes a bag that may contain a food item. The bag has a pouch section a flap that closes the pouch section. The flap defines a serving surface when the flap is opened. Thus, the serving surface supports the food item thereby facilitating the food item to be consumed.

A packaging bag includes a cutting guide band extending along a transverse direction. The cutting guide band includes, a first guide band having first cut lines that are inclined at a predetermined angle with respect to the transverse direction; a second guide band having second cut lines that are inclined at a predetermined angle in a direction opposite a direction of the first cut lines with respect to the transverse direction; and a third guide band having third cut lines that are inclined at a predetermined angle in the same direction as the direction of the first cut lines with respect to the transverse direction. The cutting guide band has a fourth cut line between the first guide band and the second guide band and/or between the second guide band and the third guide band, the fourth cut line being perforated and extending along the transverse direction.
