Epoxy resin does not adhere well to most plastics, including polyethylene and polypropylene plastics commonly used in plastic containers. Plastics with a low surface energy, like polyethylene and polypropylene, have poor adhesion to resin. This means that epoxy resin may not stick or form a strong bond with plastic containers made from these materials. If you are looking to stick plastic containers together, it is recommended to use a plastic-specific adhesive or explore other bonding options suitable for plastic materials.
