Understanding Common Terminology in Flexible Packaging Packaging > 자유게시판

Shrink film wrapping is a widely utilized method in multiple industries, particularly for cosmetics. Despite its ubiquity, many people are unfamiliar with the language used in this industry. In this article, we will break down some essential terms associated with Flexible packaging wrapping.

One of the most primary terms you will meet is 'film gauge', which refers to the caliber of the shrink material. Typical film gauges cover from 1 to 10 mils, with the thinner gauge suggesting a thinner film. Thinner films are generally more suitable for more compact products, while thicker films are employed for encompassing or more massive items.

Another critical term is 'film lay-flat,', which assesses the breadth of the film after it has been shrunk and smoothed. This characteristic is crucial when selecting a shrink material, as it must fit within the securing machinery or vessels. 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 common term you may have noticed is 'shrink ratio', which points the decrease in film size after contracting. Most shrink films have a contraction rate of 2-4:1, indicating that a 12-inch long film will contract to 3-6 inches once it has been condensed at the correct temperature.

'Quadpack' and 'quad' are terms often employed in conjunction with in shrink packaging. However, the terms refer to unique designs. Clamshell wrapping is customarily used for miniature to medium-sized items, such as personal care products. On the other hand, quad wrapping involves four surfaces of film that are shrunk to build a polygonal or rectangular box for more substantial items.

Another essential principle in shrink film securing is 'orientation', which points to the alignment of the film's polymer chains. In packaging, an unoriented film will offer a higher amount of strength and pliability, نایلون شرینگ making it suitable for products that are prone to tension or effect, such as bottles. A uniaxially or biaxially oriented film, on the other hand, has been elongated and oriented in different directions, giving it enhanced lucidity, barrier and physical properties.

In conclusion, appreciating the terminology associated with shrink film packaging can materially augment your knowledge and appreciation of this broadly used securing method. From thickness to direction, knowledge with these expressions can make it easier to understand the securing process and select the suitable shrink film for your unique product requirements.
