PETG (Polyethylene Terephthalate Glycol), OPS (Oriented Polystyrene), PVC (Polyvinyl Chloride), and PLA (Polylactic Acid) are different types of materials that can be used for shrink sleeve labels in bottle wrapping. Here’s a breakdown of each material:
- PETG Shrink Sleeve Labels: PETG is a clear, rigid, and recyclable plastic material. PETG shrink sleeve labels provide excellent clarity, high tensile strength, and resistance to impact. They offer good printability and are suitable for various bottle shapes and sizes. PETG labels are widely used in the beverage industry due to their durability and ability to withstand temperature fluctuations.
- OPS Shrink Sleeve Labels: OPS is a recyclable, clear, and rigid polystyrene material. OPS shrink sleeve labels offer excellent clarity and gloss, allowing for vibrant print designs. They have good shrinkability, conforming tightly to the shape of the bottle. OPS labels are commonly used for food and beverage packaging due to their visual appeal and cost-effectiveness.
- PVC Shrink Sleeve Labels: PVC is a widely used plastic material known for its flexibility and clarity. PVC shrink sleeve labels offer excellent shrinkability and conformability to different bottle shapes. They provide good printability and durability. However, it’s important to note that PVC is not considered an eco-friendly material due to its environmental impact during production and disposal.
- PLA Shrink Sleeve Labels: PLA is a biodegradable and compostable material made from renewable resources, such as corn starch or sugarcane. PLA shrink sleeve labels offer good shrinkability and printability. They are an eco-friendly alternative to traditional plastic labels, as they break down naturally in composting conditions. However, PLA labels may have limitations in terms of heat resistance and durability compared to other materials.
