Understanding Common Language in Shrink Film Sealing > 자유게시판

Shrink film securing is a widely populated method in various fields, particularly for pharmaceuticals. Despite its popularity, many people are oblivious with the language used in this sector. In this article, we will break down some key terms associated with shrink film packaging.

One of the most primary terms you will meet is 'film gauge', which refers to the thickness of the shrink film. Typical film gauges range from 1 to 10 mils, with the lower gauge indicating a thinner film. Thinner films are generally more suitable for شیرینگ پلی اتیلن more compact products, while thicker films are used for more extensive or bulkier items.

Another critical term is 'film lay-flat,', which assesses the breadth of the film after it has been contracted and aligned. This parameter is significant when opting a shrink film, as it must accommodate within the wrapping machinery or receptacles. For instance, a film with a lay-flat of 12 inches may not shrink to the desired 6 inches due to the material's elasticity.

A shared term you may have seen is 'shrink ratio', which indicates the decrease in film size after condensing. Most shrink films have a shrink ratio of 2-4:1, suggesting that a 12-inch long film will contract to 3-6 inches once it has been condensed at the suitable temperature.

'Clamshell' and 'clamshell' are terms often used alternatively in shrink packaging. However, the terms refer to different designs. Clamshell securing is commonly used for compact to moderate-sized items, such as food portions. On the other hand, quad wrapping involves four facings of material that are shrunk to form a rectangular or box-like box for bulkier items.

Another essential idea in shrink film securing is 'orientation', which refers to the alignment of the film's molecular chains. In wrapping, an unstructured film will offer a higher amount of tenacity and flexibility, making it fitting for products that are liable to tension or effect, such as bottles. A uniaxially or biaxially oriented film, on the other hand, has been extended and aligned in unique directions, giving it improved visibility, barrier and operational properties.

In end, appreciating the terminology associated with shrink film wrapping can significantly enhance your comprehension and appreciation of this broadly used securing method. From film gauge to alignment, familiarity with these phrases can enable it simpler to explore the securing process and choose the ideal shrink material for your unique product needs.
