Composite film is widely used as food packaging material due to its superior barrier property, impact resistance and other mechanical properties better than mono film. This article discusses the composite packaging film for meat products. The compound fastness between the mono layers of the composite packaging film is measured by the peel strength, which is [...]

The heat seal strength, refers to the strength of the seal within the flexible barrier materials and can be used to determine consistency within the seal, as well as evaluation of the opening force of the package system. Usually the heat seal strength depends on those heat seal parameters including sealing temperature, sealing pressure and [...]

Toothpaste is one daily necessity in people’s life. Now there is a variety of toothpaste on the market and most of those products are packed in flexible tubes. The most common toothpaste tubes are mainly made of plastics or aluminum plastic composite materials. The barrier layer of the plastic tube is EVOH, while the barrier [...]

There are two main categories of infusion bags: PVC and Non-PVC. Today most of the non-PVC infusion bags are made of multi-layer copolymerized compound membrane, which contains PP, PE, PA and SEBS, etc. Non-PVC is the safest material of infusion bag by now. It is free of plasticizer, which doesn’t adsorb or react with the [...]

Infusion bags are widely used in clinical treatment with which the medicine can be directly applied to the venous blood increasing therapeutic effect. There are two main categories of infusion bags: PVC and Non-PVC. Today most of the non-PVC infusion bags are made of multi-layer copolymerized compound membrane, which contains PP, PE, PA and SEBS, [...]

Cartons are usually used to pack the pharmaceuticals, which may suffer squeezing, impacting or stacking in transportation. If the carton has insufficient compression resistance, it may be deformed or even crushed. Therefore, it is necessary to test the compression resistance of those cartons before using them for pharmaceuticals so that they can protect the pharmaceuticals [...]

Aluminized laminated film is one very common packaging material that is used for pharmaceuticals, which is produced by dry lamination or extrusion lamination of multiple layers of monolayer. Generally, the mechanical property and barrier property of the laminated film is better than those of monolayer film. The compound fastness between the mono layers of the [...]

Stretch wrap or stretch film is a highly stretchable plastic film that is wrapped around items. The elastic recovery keeps the items tightly bound. In contrast, shrink wrap is applied loosely around an item and shrinks tightly with heat. It is frequently used to unitize pallet loads but also may be used for bundling smaller [...]

Biscuits are commonly eaten as snack food and are in general, made with wheat flour or oats, and sweetened with sugar or honey. Varieties may contain chocolate, fruit, jam, nuts, ginger and other ingredients. The sealing edges of the packaging bags for biscuit should have proper heat seal strength. To be specific, the seal strength [...]

The waterproof overshoes are new product that are emerging in recent years, which use natural rubber added by new type durable slip-resistant additives as raw material, combining the advantages of rubber boots and disposable plastic shoe cover. The waterproof overshoes are lighter than rubber boots and easy to carry. In rainy or snowy days, shoes [...]
