摘要:
A reclosable package comprises a first panel (12) having first and second side sections and a second panel (14) having first and second side sections (18a, 18b). The first panel opposes the second panel and is joined to the second panel along the first and second side sections. A bottom (16) extends between the first and second side sections of the first and second panels with the first and second panels joined to each other. A mouth is disposed opposite the bottom and extends between the first and second side sections of the first and second panels. A closure member extends along the mouth, with the closure member including a first fin (28a) joined to the first panel and a second fin (28b) joined to the second panel. A sealing member (35) having a first and second ends is disposed proximate the mouth. The ends of the sealing member can be attached to the fin (28b) or panel (14) such that at least one of the first end or second ends of the sealing member is attached with a peelable seal (32).

A fill-through-the-top reclosable package includes first and second opposing body panels joined to each other along a pair of sides and a bottom bridging the pair of sides. The package is provided with a reclosable fastener extending along a package top disposed opposite the bottom. The fastener includes first and second opposing tracks. The first track includes a male profile, while the second track includes a female profile adapted to releasably interlock with the male profile. To provide tamper evidence, the first and second tracks may be joined to each other along an area of weakness. When making the package, the first track is first attached to the first panel, the package is filled with a product via a fill opening between the second track and the second panel, and then the second track is attached to the second panel.

A slider-operated fastener (10) comprises first and second opposing tracks (12, 14) including respective first and second interlocking profiles (16, 18) and respective first and second fins (20, 22) extending downward from the respective first and second profiles (16, 18). The first and second fins (20, 22) are sealed to each other by a plurality of spaced preseals (28). After generating each preseal (28), a notch (38) is formed in the profiles and upper portions of the fins (20, 22) at the generated preseal (28). To install a slider (40) is initially positioned within the respective notch (38) and then threaded onto the fastener (10) in response to relative movement of the slider (40) and the fastener. Either before or after the steps of forming each preseal (28) and respective notch (38) and installing the respective slider (40), the fastener (10) is attached to a moving web (50) of plastic film (52). The fastener-carrying web (50) is later folded and sealed to form individual plastic bags (80).

A blowing agent blend for making thermoplastic polymer foams includes methyl formate. The blowing agent blend can further comprise at least one co- blowing agent. The co-blowing agent is either a physical co-blowing agent (e.g. an inorganic agent, a hydrocarbon, a halogenated hydrocarbon, a hydrocarbon with polar, functional group(s), water or any combination thereof), or a chemical co-blowing agent, or combinations thereof. The thermoplastic polymer foam can be an alkenyl aromatic polymer foam, e.g. a polystyrene foam. The blowing agent blend includes methyl formate and one or more co-blowing agents. The methyl formate-based blowing agent blends produce dimensionally stable foams that have improved resistance to flame spread. A process for the preparation of such foams is also provided.
摘要:
A web for use as wrap material, lidding material or in packages with active agents. Generally, each disclosed structure includes at least a first material layer made of a barrier material; and an active agent carried by the first material layer. Webs in accordance with the invention can further include a second material layer disposed adjacent the first material layer, wherein the second material layer has a predetermined material property, such as permeability, cling and/or sealing characteristics.
摘要:
A container assembly comprises first and second containers. The first container (10) includes a first body portion (12) and a first rim (14). The first rim (14) has a first plurality of ribs (20) projecting generally upwardly therefrom such that first spaces are formed between adjacent ribs. The first rim (14) has a generally convex shape. The second container (110) includes a second body portion (112) and a second rim (114). The second rim (114) has a second plurality of ribs (120) projecting generally downwardly therefrom such that second spaces are formed between adjacent ribs. The second rim (114) has a generally concave shape. The first and second rims have shapes that correspond with each other when locked. The first and second containers are adapted to be releasably lockable by fitting the second plurality of ribs (120) into respective ones of the first plurality of ribs (20) and fitting the first spaces into respective ones of the second spaces.
摘要:
Packages with active agents are described. Generally, each disclosed package (10) has a pair of opposing body panels (16, 18) joined together along a pair of opposing sides and a bottom bridging the sides, a reclosable fastener (14) extending along a mouth formed opposite the bottom, and an active agent (50) . The active agent (50) is associated with at least one of the body panels (16, 18) and includes a freshness-extension agent to inhibit spoilage of perishable products disposed in the package and manage, mask, and/or neutralize odors from such products disposed in the package.
摘要:
A zipper arrangement for use in manufacturing thermoplastic bags that includes a zipper and at least one slider. The zipper includes first and second opposing tracks. The first track has a first profile and the second track has a second profile. The first and second profiles are releasably engageable to each other. The first track has one or more spaced primary notches interrupting the first profile. At least one slider is inserted onto the first profile via a respective one of the primary notches. The slider is adapted to engage and disengage the first and second profiles in response to movement along the zipper. The second track may have one or more spaced primary notches interrupting the second profile. The spaced primary notches of the second track are generally aligned to respective ones of the primary notches of the first track. At least one slider is inserted onto the aligned pairs of primary notches via a respective one of the generally aligned notches.
