Films used for food storage must prioritize safety. Therefore, choosing the appropriate packaging film is of utmost importance.

Why are polyolefins the best shrink film for packaging food?

When packaging food, safety must be a top priority. Not all films are suitable for food packaging. Polyolefin packaging film is the best choice for food packaging because it is safe. POF packaging film meets FDA standards and is approved for direct contact with food. It is ideal for packaging vegetables, meat, cheese, and other food items.

In addition to safety, polyolefin shrink film has many other advantages. It has good transparency, appropriate toughness and strength, and can protect food from external damage. It also has good heat shrinkability and can tightly wrap food to achieve a good sealing effect. Polyolefin shrink film is very important in the food packaging industry and is irreplaceable.

Benefits of POF Shrink Films for Food Packaging

POF shrink film has many advantages for food packaging. It is more suitable for food packaging than PVC shrink film, as it insulates against temperature and water vapor, saves on roll consumption, and does not need to be replaced frequently.

• High transparency: Bright and glossy, it gives food a lasting visual impact and appeal. Whether it is meat or vegetables, it attracts consumers.
• Highly recyclable: The polyolefin molecular structure makes it a fully recyclable product, enhancing corporate return on investment and reducing environmental impact.
• High efficiency: Fast and uniform shrinkage saves time on automatic packaging lines and achieves uniform packaging.
• Flexible and durable: Can handle sharp-edged foods such as cookies. Protects product safety and helps shape brand image. At the same time, it is highly functional and can be used to package a variety of foods, including bread, meat, fish, and poultry.
• Cost-effective: POF shrink film is affordable, with a 12-inch, 45-gauge roll of half-folded product selling for only about $150, making it ideal for unitized products. Cross-linked POF shrink film is suitable for fast packaging applications, enhancing strength without compromising transparency.
• Excellent physical properties: It can withstand temperature fluctuations and has superior tensile strength and tear resistance. Pre-perforated POF shrink film reduces air pocket formation and provides a smooth and uniform shrink surface. It seals securely to prevent leakage and contamination, and is puncture resistant, adapting to products of various shapes and sizes to meet the diverse needs of food packaging.

The vent holes and non-barrier properties of standard heat shrink wrap materials prevent an air-tight seal.

Shrink packaging helps keep food fresh. It maintains a certain level of freshness in food. It is flexible and fits well around the shape of food, reducing oxygen exposure. Most shrink packaging has vent holes. The vent holes and non-barrier properties of standard heat shrink wrap materials prevent an air-tight seal.

Is PVC Shrink Wrap Food Safe?

PVC shrink packaging releases harmful substances when heated and cannot come into direct contact with food. It is not approved by the FDA for use in food packaging. If food is packaged in a box, the box can be covered with PVC so that the food does not come into direct contact with the PVC.

In comparison, polyolefin shrink packaging is safer and complies with food safety standards. Some food films use food-grade PVC materials, but to ensure safety, it is still necessary to ask the supplier to confirm whether they can be used

Is Saran Wrap the Same as Shrink Wrap? 

Food wrap and shrink wrap are different.

Shrink wrap shrinks when exposed to heat and is a type of plastic material. It can be used to wrap products and conform to their shapes. It is commonly used for product packaging, as it prevents tampering, secures products, and extends shelf life.

Plastic wrap is generally made of polyethylene. It does not contain BPA and is non-toxic to food. However, it melts when heated and is mainly used for simple daily food preservation, such as covering bowls and dishes, and preserving vegetables and fruits.

The two differ in terms of material properties, usage, and application scenarios.

What are everyday shrink wrap products used with consumable foods? 

There are several common types of shrink packaging for food.

• Shrink bags: The product is completely wrapped with a single seal. Commonly used for small batches of cookies or baked goods.
• Centerfold Shrink Wrap: Folded lengthwise in the middle and rolled up, allowing for quick food packaging.
• Barrier Shrink Wrap: Blocks air and oxygen, mostly in the form of bags, and can be completely sealed with a single seal.
• Singlewound Shrink Wrap: Flat, can be used to package a variety of consumer goods. For example, meat on foam trays, takeout pizza, baked goods, and agricultural products.

These packages have their own characteristics, providing a variety of options to protect food quality and extend shelf life.
