Flat poly bags are open-ended polyethylene bags used for protecting, storing, and transporting a wide variety of products. They provide moisture and dust barriers while allowing product visibility, making them ideal for retail merchandise, textile storage, food packaging, and industrial parts protection. What mil thickness is best for garment bags? 1.5 mil poly bags are suitable for most garment storage applications including dresses, suits, and coats. This thickness provides adequate protection against dust and light handling while remaining economical. For heavy garments with embellishments or frequent handling, 2 mil or thicker options offer increased durability. Can these bags be heat sealed? Yes, LDPE poly bags are heat-sealable using impulse sealers, constant heat sealers, or hand-held heat sealing tools. Heat sealing creates a permanent, tamper-evident closure ideal for retail packaging and long-term storage. Sealing temperature and dwell time should be adjusted based on bag thickness and sealer type.
