Methods and systems for delivering biological products to different surgical sites during surgery are described. The biological product is encapsulated or contained within a containment system comprising a carrier such as collagen carrier. The containment system may be formed of water soluble polymers that are natural, synthetic or semisynthetic, provided into films that may be made or molded into various shapes and sizes, and that may be manipulated to confer specific properties of such films. The water soluble films may be processed into capsules, packets or other containers.
