ABSTRACT:
A thermoplastic film package having a plurality of tightly held articles, such as beverage bottles, is provided with a thermoplastic film handle and with an upper surface permitting opening of the package in a manner which facilitates removal of all or a portion of the articles from the package and return of articles to the package. The positions of attachment of the handle to the package in relation to the opened upper surface of the package enable the handle to assist in maintaining the integrity and usefulness of the package after it is opened, even though it is made of thin thermoplastic film. The opened package is thus suitable for carrying all or only a portion of the contents by using the handle. The end portions of the handle can be attached to the package by a process involving preliminary tacking and subsequent heating by contact with a hot gas in a film-shrinking operation. Secure attachment of the handle is obtained even though the contour of the area of the package to which the attachment is made is uneven and varies from one package to another in a given packaging operation.
