## Abstract

We say that two hypergraphs H_{1} and H_{2} with v vertices each can be packed if there are edge disjoint hypergraphs H_{1}^{′}and H_{2}^{′}on the same set V of v vertices, where H_{i}^{′}is isomorphic to H_{i}.It is shown that for every fixed integers k and t, where t≤k≤2t-2 and for all sufficiently large v there are two (t, k, v) partial designs that cannot be packed. Moreover, there are two isomorphic partial (t, k, v)-designs that cannot be packed. It is also shown that for every fixed k≥2t-1 and for all sufficiently large v there is a (λ_{1}, t,k,v) partial design and a (λ_{1}, t,k,v) partial design that cannot be packed, where λ_{1} λ_{2}≤O(v^{k-2t+1}log v). Both results are nearly optimal asymptotically and answer questions of Teirlinck. The proofs are probabilistic.
