Breast milk storage bag

Breast milk storage bags, also known as breast milk preservation bags, are plastic packaging products primarily used for storing breast milk. When milk supply is abundant, mothers can express their milk and store it in these bags, refrigerating or freezing it for later use—whether to address a temporary shortage of milk or when work commitments make on-demand feeding difficult.

Security bag

As a widely used type of packaging bag, security bags are commonly employed for shipping documents and similar small items or papers. The exterior of the bag features a specialized waterproof coating, which not only minimizes damage and tearing during transit but also enhances the protection of the contents. Even in rainy conditions, rapid transportation poses no issues, ensuring that the enclosed documents remain well‑protected.

Food packaging bag

Food packaging pouches, known in English as "Food Packaging Pouches," are a type of packaging design. In everyday life, product packaging bags have emerged to facilitate food preservation and storage. A food packaging pouch refers to a thin-film container that comes into direct contact with food, used for containing and protecting it. Such pouches are typically made from PE (polyethylene) or PP (polypropylene). Almost all plastics rely on synthetic resins as their primary component; resins serve as the binding agent, holding the other ingredients together into a cohesive whole. Although various additives can modify a plastic's properties, the resin remains the fundamental factor determining the plastic's type, performance, and intended applications.
