For a 250ml large-capacity body lotion tube, the wall thickness is commonly recommended around 0.55mm to 0.75mm, depending on the tube diameter, PE structure, formula density, shoulder design, and transport requirements. If the formula is heavy, the tube is long,…
Co-extruded tubes often offer better flexibility and memory, or shape retention, because their tube body is made from continuous extruded plastic layers rather than a flat laminate sheet that is rolled and side-welded. This gives co-extruded tubes a more integrated…
The main difference between an extruded tube and a laminated tube is that an extruded tube usually has a seamless tube body, while a laminated tube normally has a visible or semi-visible side seam. This structural difference affects the overall…
To choose between ABL (Aluminum Barrier Laminate) and PBL (Plastic Barrier Laminate) tubes for toothpaste or functional skincare, brands should compare barrier requirement, product sensitivity, squeeze recovery, appearance, recyclability positioning, and cost. In simple terms, ABL is usually better when…
Industry-standard cosmetic tube diameters for hand cream and lotions commonly include 16mm, 19mm, 22mm, 25mm, 30mm, 35mm, 40mm, and 50mm. Among these, 30mm to 35mm are widely used for hand cream, while 40mm to 50mm are more common for body…
Plastic tubes can collapse or deform after filling because the pressure inside the tube becomes lower than the outside atmospheric pressure. This is often called the paneling effect. Instead of staying round and smooth, the tube body caves inward, forms…
To determine the precise tube size for high-density cosmetic pastes, brands should calculate by volume first, not by weight alone. Tube capacity is normally measured in ml, while many cosmetic formulas are sold by grams. For high-density pastes such as…
For a 50g sunscreen lotion, a common tube recommendation is usually around 35mm diameter with a tube length of about 110mm to 125mm, depending on the sunscreen density, shoulder design, cap type, and required headspace. However, there is no single…
The oxygen transmission rate (OTR) of a standard PE tube is usually much higher than that of a 5-layer EVOH tube. In practical packaging terms, this means oxygen can pass through a normal PE tube much more easily, while a…
An EVOH barrier layer is a thin high-barrier layer made from ethylene vinyl alcohol copolymer. In cosmetic tube packaging, it is usually placed inside a co-extruded multi-layer structure to reduce the transmission of oxygen, aroma, and some chemical substances. This…
