1、Designation: D 6881 03Standard Classification forStandard Plastics Industry Bulk Box/Pallet Unit SizeClassified By Bulk Density1This standard is issued under the fixed designation D 6881; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revis
2、ion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONAn ad-hoc survey in 2000 showed about 40 different box sizes in use by the plastic resin industry;th
3、e purpose for this classification is to quantify a box/pallet unit size acceptable for this industry withinthe limits of the scope.1. Scope1.1 This classification covers containers used to hold plasticresins with bulk density (Test Methods D 1895)of27to39lb/ft3(0.432 to 0.625 g/cm3).1.2 This classif
4、ication does not apply to any plastic resinswith bulk density below 27 lb/ft3(0.432 g/cm3) or above39lb/ft3(0.625 g/cm3).1.3 This standard does not apply to bulk boxes containinghazardous materials.1.4 This standard does not address box/pallet unitizationrequirements.1.5 This standard does not addre
5、ss requirements of plasticbag liners normally placed inside the corrugated bulk boxbefore filling with plastic resin.1.6 This standard does not address tamping, shaking, orother compression methods of the resin filled bulk box tocondense entrained air and increase headspace in the bulk box.1.7 This
6、standard does not address blocking and bracing orother shipping requirements normally associated with bulk boxunit deliveries.1.8 This standard does not address filled bulk box/pallet unitstack height.1.9 This standard does not address international shippingregulations of bulk box/pallet units.1.10
7、This standard does not address pallet opening sizes forpallet trucks.1.11 Units of MeasureThe value stated in either SI unitsor inch-pound units are to be regarded separately as standard.The values stated in each system may not be exact equivalents;therefore, each system shall be used independently
8、of the other.Combining values from the two systems may result in noncon-formance with the standard.1.12 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and heal
9、th practices and determine the applica-bility of regulatory requirements prior to use.1.13 This classification offers an organized collection ofinformation or a series of options and does not recommend aspecific course of action. This document cannot replace edu-cation or experience and should be us
10、ed in conjunction withprofessional judgement. Not all aspects of this classificationmay be applicable in all circumstances. This ASTM standard isnot intended to represent or replace the standard of care bywhich the adequacy of a given professional service must bejudged, nor should this document be a
11、pplied without consid-eration of a projects many unique aspects.

Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 bulk box, plastic resin, na container used to enclose,protect, hold, and transport plastic resin, with net weights ofabout 1000 to 1600 lb (453.6 to 725.7 kg); it will havesemi-rigid sidewalls that re
13、sist bulging of the sidewall whenloaded, retain the approximate size of the empty assembledbox, and prevent collapse of the container during removal ofthe product.1This classification is under the jurisdiction of ASTM Committee D10 onPackaging and is the direct responsibility of Subcommittee D10.12

16、 astack height selected by the user.3.1.2 freeboard, namount of bulk box set back from palletedge on all sides to offset the bulge of the container when filledwith resin (typically 7 to 8 % of pallet dimension).3.1.3 pinwheeling, vwhen lengthwise loading vans orcontainers, the turning of a bulk box

Significance and Use4.1 This standard classifi
18、cation will be used to:4.1.1 Standardize the package size increasing availability,versatility, and acceptability of bulk box/pallet units.4.1.2 Lower transport package manufacturing costs.4.1.3 Lower cost/lb of packaged resin because of higher netweight/package.4.1.4 Reduce environmental impact of p
19、allets and bulkboxes by reducing waste.4.1.5 Support reuse of bulk boxes and pallets throughout thesupply chain.4.1.6 Optimize lifecycle package cost.4.1.7 Improve both inbound and outbound freight cost incomparison to non-optimal packaging.4.1.8 Lower inventory/storage cost of raw materials (needle
20、ss on hand).4.1.9 Reduce warehouse space for resin storage.4.1.10 Reduce forklift trips (carrying higher weight).4.1.11 Promote multi-industry usage of common footprintboxes and pallets (examples are the automotive and chemicaldrum industry).4.1.12 Guide the first-time resin packager as to a success
21、fulbulk box/pallet unit now in use in the resin industry.4.1.13 Optimize net product weight in truckload trailer vansand oversea containers.4.2 This standard classification will be used by:4.2.1 Resin producers/converters/compounders/customersto compare with their current practice.4.2.2 Bulk box man
22、ufacturers to recommend a provencost-effective package for plastic resins in the targeted bulkdensity range.4.2.3 Pallet manufacturers as a common bulk box footprintpallet for the targeted bulk density ranges used by the plasticresin industry.4.2.4 Box liner manufacturers to size their liners to asp
23、ecified volume dimension.4.2.5 Warehouses to provide space layout plans based ondimensions of the standard box/pallet unit.5. Basis of Classification5.1 The bulk box will contain about 1000 to 1600 lb (453.6to 725.7 kg) of plastic resins with typical bulk densities of 27to 39 lb/ft3(0.432 to 0.625 g
24、/cm3).5.2 Minimum performance of the bulk box pallet unitduring pack out, storage, and transit will be specified by theuser.5.3 Total height of box, cap, and pallet (container height)equals 44 634-in. (1118 6 19 mm).5.4 Total width of pallet (container footprint width) equals45 614-in. (1143 6 6.35
25、mm).5.5 Total length of pallet (container footprint length) equals48 614-in. (1219 6 6.35 mm).5.6 Bulk box “freeboard” on all sides of the pallet will bespecified by the user.5.7 Corrugated fiberboard bulk boxes are normally used inthis application; the octagon-shaped box is preferred becauseof the
26、superior strength/capacity weight over rectangular cor-rugated boxes.5.8 Wooden pallets are typically used in this application butmay be of other materials of construction; the required foot-print will allow the user an option to choose either four- ortwo-way entry.5.9 The eight corners of the octag
27、on bulk box must besupported on top and on the bottom by the pallet; box cornersmust align top and bottom on deck boards of wooden pallets.6.

BULK BOX STANDARD CLASSIFICATION SUMMARYA1.1 Criteria in setting dimension limits include:A1.1.1 The height requirement is to insure that the doublestack container (normal fork truck lo
31、ad) will enter the oceancontainer that has an opening of 90 in. (2286 mm) at thecontainer entrance door.A1.1.2 The width requirement is to insure two containerswill fit side by side in truck vans and ocean containers withadequate space for fork truck loading. Inside ocean containerwidth equals 92 in
32、. (2337 mm).A1.1.3 The width requirement is to insure the bulk box orpallet/skid may be suitable for use in multi-industry applica-tions (for example, the automotive and chemical drum indus-tries).A1.1.4 The length requirement is to insure the bulk box orpallet/skid may be suitable for use in multi-
33、industry applica-tions (for example, the automotive and chemical drum indus-tries).A1.1.5 The weight requirement is based on the volume ofthe bulk box and bulk density of the plastic resin.APPENDIX(Nonmandatory Information)X1. GENERAL USE AND GUIDANCEX1.1 The size requirements are based on being abl
34、e to loadocean freight containers as well as truck load vans using palletswith a two-way entry (no “pinwheeling” of the load isnecessary). User may specify pallets with four-way entry.X1.2 Since the box will be used by a wide variety of userswith different storage and transit requirements, each user
35、 mayutilize their own performance standards and specifications.X1.3 Organizations that may be interested in this standardinclude:X1.3.1 Society of Plastic Engineers.X1.3.2 National Wooden Pallet and Container Association.X1.3.3 Technical Association of the Pulp and Paper Indus-try.X1.3.4 American Pl
