Heat Shrink PVC Capsules for Standard Bottles — Open Top Design

Introduction

For many bottled products, PVC capsules without a top disk are a popular heat-shrink capsule shape. Because of its open-top design and absence of a top disc, this kind of capsule simplifies application and manufacturing while providing whole neck coverage.

Structure and Materials

The capsules are made of heat-shrinkable PVC material. When heated during application, the film forms a smooth and uniform fit around the bottle’s neck. In addition to simplifying equipment setup and lowering the number of alignment steps required during shrinking, the absence of a top disc ensures dependable neck covering and protection.Modern bottling operations now include wine capsule design, which combines visual consistency, production compatibility, and material selection. In a variety of bottle shapes and product categories, capsules are increasingly used for equipment integration, decorative display, and functional sealing. This guide lists 7 subtypes of capsules in addition to seven main categories, arranged according to production process needs, application fit, and material type.

Decorative Options

Although they have a simple form, these capsules offer a lot of decorative options. Complex designs, business logos, color schemes, and regulatory markers can be directly applied to the film thanks to the skirt surface’s full roll-to-roll printing capability. Hot stamping methods, which can be used on metallic surfaces in one or two colors depending on branding requirements, can further improve the decorative appearance.

Easy Opening Features

To make the skirt more user-friendly, various perforation patterns can be added. Perforation lines can be deployed horizontally, vertically, or in combination designs to offer controlled capsule removal. T-shaped holes are also available for simpler opening. Also, there are options for adding tear tape in both vertical and horizontal directions, which ensures a straightforward and clean capsule removal while preserving the bottle’s appearance prior to opening.

Production Process

Roll-fed PVC film is printed to begin the manufacturing process in compliance with design specifications. Perforations and in-line tear tapes are used all the way through the processing procedure. Once the film is precisely trimmed to size, it is molded into cylindrical sleeves. For both automated and human shrink application techniques, these finished sleeves come in stacked or continuous roll forms.

Application Scope

PVC capsules without a top disk are commonly used in table wines, spirits, cooking oils, and specialty packaged goods. Their combination of facile application, consistent shrink behavior, and flexible decoration makes them suitable for both high-volume industrial manufacture and specialist bottling operations.
