Dị ka a maara nke ọma, ihe omume nke "akpụkpọ anụ shark" na-emekarị mgbe a na-ewepụ polyethylene mkpuchi ma ọ bụ eriri na eriri, karịsịa mgbe ị na-ewepụ polyethylene dị ala dị ala (LLDPE) ma ọ bụ polyethylene ultra-low density (ULDPE ma ọ bụ POE). Ihe polyethylene na-ejikọta ya na-apụ apụ (ma peroxide cross-linking ma ọ bụ silane cross-linking) na-enwekwa mgbe ụfọdụ ihe omume "akpụkpọ anụ shark", n'ihi nlebara anya nke ọma nke usoro mmanu mmanu na usoro ihe. Omume mba ụwa dị ugbu a bụ ịgbakwunye ọnụọgụ nke fluoropolymers na usoro ahụ, mana ọnụ ahịa ya dị elu na ngwa ahụ nwere oke.

Na obere ego nkeultra-high molecular arọ silicone(0.1-0.2%) na polyethylene ma ọ bụ polyethylene jikọtara ya nwere ike igbochi ọgbọ nke "akpụkpọ anụ shark" nke ọma.
