Abstract：Inorder toimprove thereliabilityof logistics packaging，the preparationand adhesive properties of silicone-modified epoxy resin encapsulants for logistics packaging were studied.The main raw materials were alyl glycidyl ether and1，1，3，3ltetramethyldisiloxane，and theorganosilicon prepolymer EP-Si was synthesized by siliconhydrogenation reaction as a toughening agent.EP-Si was mixed with bisphenol A-type epoxy resinand curing agent to prepare encapsulant specimens.Studies showed that the adhesive strength of encapsulant was highest when EP-Si was usedat 4.8 phr.EP- Si could toughen E-44 epoxy resin，the modified encapsulant section was rough，not easy to crack，the contact angle was increased，thewater absorptionrate was reduced，and the moistureproof performance was good. At 50， and at room temperature ，the encapsulant ensured a good encapsulation of the logistics package.
