Skin Pack

Vacuum skin packaging (Skin Pack) is a packaging method that uses vacuum technology to tightly conform a transparent plastic film to the product surface. The principle is: place the product on a cardboard or tray, cover it with a heated and softened plastic film, and by applying vacuum, the film stretches and adheres to the product's shape, creating a 'second skin' effect. This packaging is widely used for small industrial and consumer goods such as hardware tools, electronic components, automotive parts, medical devices, and toys. It provides moisture, dust, rust, and static protection while displaying the product's appearance. Usage scenarios include: products requiring high transparency and secure protection, retail display, or transport protection. Precautions: the film must be compatible with the product to avoid punctures from sharp edges; for fragile or flexible products, vacuum level must be controlled; after packaging, seal integrity must be checked. Differences from other terms: unlike 'Blister Pack', Skin Pack film completely conforms to the product without a separate blister; unlike 'Vacuum Pack', which is typically used for food, where the film clings to the product but has no rigid backing. In foreign trade, it is often necessary to specify packaging method, material specifications (e.g., PVC/PE film thickness), backing material, and compliance with environmental requirements.
