Precision die-cutting creates exact tube dimensions that accommodate products ranging from 30ml travel sizes to 100ml full-size formats without excessive movement or wasted space. The shallow depth maintains slim profile shipping envelopes while raised side walls provide lateral protection against impacts. Unlike thermoformed plastic clamshells that require heat sealing or cardboard sleeves that slide apart easily, this molded configuration holds tubes firmly through friction fit and geometric containment. The material's shock-absorbing properties protect delicate dispensing valves and airless pump systems from the pressure fluctuations and mechanical stress encountered during logistics handling. Skincare formulators using glass tubes or aluminum packaging gain additional security from the cushioning effect that prevents breakage without bubble wrap.
