Airline vomit bags are mainly made of multi-layer composite materials, the core of which is a specially treated food-grade coated paper. This paper substrate is usually based on high-strength virgin wood pulp paper, and the inner layer is tightly attached to a very thin PE or PP plastic coating. This coating is crucial, giving the airline vomit bag excellent anti-penetration function, which can instantly block liquids and dirt, and prevent leakage from soiling passengers' clothes or the cabin environment. The outer layer of paper provides good moisture absorption, is easy to grip, feels relatively comfortable, and ensures that the printed logo is clear and durable.
In terms of production technology, the selection of materials is extremely strict and must meet the safety and hygiene standards of the aviation industry. The inner plastic film must reach the food contact grade non-toxic and harmless certification to ensure that no harmful substances will be precipitated when vomit comes into contact. The paper part has sufficient toughness to withstand the instantaneous impact force during vomiting and is not easy to break, and can be designed with an indentation at the bag mouth for quick deployment and use. The manufactured airline vomit bags must undergo strict sealing, load-bearing and chemical compatibility tests to ensure stable and reliable performance in a small space and under pressure changes. Some high-end versions also add activated carbon interlayers to assist in absorbing odors.
This unique design makes the airline vomit bag a model of emergency hygiene products on board. Its lightness, portability, instant unfolding and reliable sealing greatly alleviate the embarrassment of passengers when they suddenly feel unwell. When using it, just tear open the seal of the bag and unfold the bag. After use, it can seal itself to prevent odor overflow and secondary pollution. A small airline vomit bag, with its scientific material combination and careful structural design, silently guards the hygiene and dignity of the journey, and is an indispensable detail guarantee in aviation safety services.
