In the bacon packaging process, it is crucial to choose the right vacuum bag material. In response to this problem, Suzhou Lianzong Packaging will be carried out from the following aspects:
1.Characteristics of bacon and vacuum packaging requirements.
Bacon is a food product made from pork cured with high salt and moisture content. These characteristics need to be taken into account when vacuum packaging to prevent food spoilage and bacterial growth. Therefore, the vacuum bag material should have the characteristics of good sealing performance, moisture-proof and anti-oxidation.
2.Commonly used vacuum bag materials and their characteristics.
At present, the commonly used vacuum bag materials on the market include: PE, PA, EVOH, PVDC, etc. Each of these materials has its own characteristics and is suitable for different food packaging needs.
a) PE film.
PE film is a common plastic film with excellent barrier properties and transparency. It is effective in preventing the penetration of water vapor and oxygen, but is less permeable to carbon dioxide and odors. PE film** is cheap and suitable for food packaging with low requirements for packaging costs.
b) PA membrane.
PA membrane is nylon membrane, which has high tensile strength and impact strength. It has good barrier properties against water vapor, oxygen and odor, but it is relatively high. PA film is suitable for packaging high value-added foods, such as high-grade bacon, etc.
c) EVOH membrane.
EVOH film is a high barrier film, which has good barrier properties for oxygen, water vapor, carbon dioxide, etc. At the same time, it also has good transparency and gloss, which is suitable for food with high packaging appearance requirements. However, EVOH films** are higher and are mainly used for the packaging of high value-added foods.
d) PVDC membranes.
PVDC film is a kind of film with excellent barrier properties, which has good barrier properties for oxygen, water vapor, odor, etc. At the same time, it also has good transparency and heat sealing performance. PVDC film** is moderate, suitable for food packaging with high packaging requirements.
3.It is recommended to use vacuum bag material for bacon packaging.
According to the characteristics of bacon and the common vacuum bag materials on the market, we make the following recommendations:
a) For ordinary bacon packaging, you can choose PE film or PA film as the vacuum bag material. Both of these materials have good sealing performance and barrier performance, which can meet the requirements of ordinary bacon packaging.
b) For bacon packaging with high added value or high requirements for appearance, EVOH film or PVDC film can be selected as the vacuum bag material. Both materials have good barrier properties and transparency, which can improve the appearance and shelf life of the product.
c) When choosing a vacuum bag material, it is also necessary to consider the packaging cost and environmental factors. For mass-produced bacon packaging, a lower-cost PE film can be chosenFor small-scale or high-end market demand for bacon packaging, environmentally friendly materials such as PA film, EVOH film or PVDC film with higher cost can be selected.
In short, when choosing the vacuum bag material for bacon packaging, it is necessary to comprehensively consider factors such as food characteristics, packaging requirements, cost and environmental protection. The right choice of materials can ensure the safety, shelf life and appearance quality of bacon, and enhance the market competitiveness of the product.
