The New England Journal of Medicine reported that the causal agent of COVID 19 is able to persist for up to 24 hours on cardboard, in experimental settings.
The risks of transmission of coronavirus from a package is very low because the virus is generally thought to be spread most often by respiratory droplets that are transmitted by sneezing and coughing.

I think this is very weak than other transmission media, otherwise you have to put on the gloves before receiving the packages.
There is an ongoing study in the Coronavirus-hotspot Heinsberg (Germany). In a podcast the virologist Hendrik Streeck explained that they were not able to find active virus on surfaces like door handles in households with several infected persons. Also, until now they couldn't confirm any transmissions in supermarkets. So the risk is almost 0 with the package, just beware of the postman.
Very less possibility of Covid 19 transmission through packages delivered through postal/courier. Please find below reasons,
1. Extreme ambient condition variation during transportation including temperature, moisture, mechanical stress etc. all are bad for Virus survival/functionality.
2. Harsh/reactive species generated from packaging material because of temperature are bad for the virus.
3. UV light and from sun if packages handled openly.
4. Normally packages delivered in more than 24 hour time.
Considering all these factors risk of transmission is very low, we can not consider is as zero risk, so to avoid risk following measures has to be taken for packages
1. Postal/courier companies should use sanitizer showers for packages.
2. Users should sanitize parcel before taking it inside home.
3. Should be handled in home after a minimum 24 hours delay.
Hope I have covered most points
Dear Dr. in this RE open question we attempt to analyse the Lombardia dramatic event in mortality rate, but now, also for other Europea key areas (Madrid, Catalonia, London, Netherlands). Some work hypothesis are: oro-fecal transmission; Diamond Princess passengers return as spreaders (according to insufficient quarantine and positive intestinal tests but negative in nasal-oral tests); additional animal reservoirs; urban-river effect.

Dmitry Nikolaenko can you please stop spamming questions with your preprint, especially when it does not address the question in hand.
If you want to get people involved in your work open your own discussion on Researchgate please.
The level of risk of infection with SARS-CoV-2 coronavirus causing Covid-19 disease from the collection of parcels or letters delivered via the postal system is determined by several important factors, which include, in particular, the following issues:
1. Does the parcel transport logistics system take into account all the necessary anti-pandemic and sanitary safety rules and the recommendations of public institutions dealing with the current pandemic?
2. How are certain products packed in the packages sent? E.g. are the paper boxes additionally covered with an airtight film that can be removed efficiently?
3. Type of material and type of surface of the material from which the packaging is made. Time of parcel delivery and / or delivery by courier. Research shows that SARS-CoV-2 Coronavirus on plastic surfaces can last up to 72 hours. Depending on the type of material, level of humidity, surface structure of the material, temperature, this time can vary significantly.
4. Standards of anti-pandemic and sanitary security principles applied in practice by couriers delivering packages and parcels.
5. The scale of the epidemic's development in a region of a specific country in which specific products are prepared for packaging, then they are packed and shipped.
6. How does the recipient of the package, i.e. the person receiving the package from the courier, receive and unpack this package? Does it do so with due caution and appropriate anti-pandemic and sanitary safety recommendations? Does he unpack the package at home or away? Does he unpack the package immediately after receiving it from the courier or wait a few hours to increase the likelihood of automatic deactivation of any virus particles that may be on the packaging?

Do not worry about the package. First think about the parcel delivery boy.
Health organizations have not documented the spread of COVID-19 via mail or package delivery.
