Compound material, container and sterile product

A sterile container (1) comprising a container body (40) having inner surfaces (2, 4) delimiting a containment compartment (6), wherein at least part of said surfaces (2, 4) is made of a compound material comprising a thermoplastic polymer, a first zeolite and a second zeolite homogeneously dispersed in the thermoplastic polymer, each of said zeolites having a micrometric particle size distribution and delimiting reticular voids in which bactericidal and/or bacteriostatic metal ions releasable from said zeolite are housed;

• wherein:
• the first and second zeolites are different,
• the compound material comprises—per 100 grams of thermoplastic polymer—an amount of first zeolite equal to or greater than 5.5% by weight (% wt), and an amount of second zeolite equal to or greater than 5.5% by weight (% wt),
• the first zeolite consists of:
• (i) sodalite, mordenite, analcite, clinoptilolite, chabazite, erionite, zeolite A, zeolite X, zeolite Y, zeolite T, or any mixture thereof, and (ii) silver and copper metal ions,
• the second zeolite consists of (i) sodalite, mordenite, analcite, clinoptilolite, chabazite, erionite, zeolite A, zeolite X, zeolite Y, zeolite T, or any mixture thereof, and (ii) silver and zinc metal ions, and
• the following formula is valid:
• 0.05<(Ag1+Ag2)/(Cu1+Zn2)<0.8
• wherein:
• Ag1 is the percentage by weight (% wt) of the silver ions with respect to the weight of the first zeolite;
• Ag2 is the percentage by weight (% wt) of the silver ions with respect to the weight of the second zeolite;
• Cu1 is the percentage by weight (% wt) of the copper ions with respect to the weight of the first zeolite;
• and
• Zn2 is the percentage by weight (% wt) of the zinc ions with respect to the weight of the second zeolite.
